As much as we try to plan for everything, there are just some times when the strangest, most unexpected , and oftentimes downright awful stuff can happen and totally derail us.
That’s exactly what happened to the unfortunate people in this list. I guess it’ll just mean that they’ll have to figure out how to change their plans pretty quickly.
“The pedal of my bicycle randomly decided to break and now I have to walk over an hour home.”

There’s nothing worse than being stranded far away from home when you were planning to ride your bike. Hopefully it didn’t rain on OP.
“Went to the doctor for a physical, came out with anxiety, depression and Type 1 diabetes.”

I don’t think anyone really plans for diabetes, especially not Type 1. But hopefully if OP can manage that, they can improve their mental health, too…
“Happy Cinco de Mayo! …some of us didn’t bring lunch…”

Well, it does say it was rescheduled, so at least they know what Cinco de Mayo means. But still… maybe they should’ve said something sooner. Since some people didn’t bring a lunch and all.
“Just started using our downstairs bedroom to save on electricity at our rental. Got a huge storm and water started coming up through the carpet. I’ve pulled over 12 buckets up.”

Oh man, that’s both nasty and horrible.
“Was excited to get my new monitor since I’ve been down one for two months but it came broken.”

Of course, you try to replace a broken monitor and get… a broken monitor. That’s just how the universe works sometimes.
“Yesterday, my dog jumped up and her head collided with my chin, hard enough to make me see stars and break one of my front teeth in half.”

As much as we love our dogs, they definitely don’t know their own strength sometimes. Ouch!
“One of the cooks lost an Airpod down this drain today.”

Something tells me that cook isn’t going to be getting that Airpod back anytime soon… or ever… It might be time to invest in a new pair of earbuds.
“Drove 15 mins out of my way to charge my car, only to find this.”

Electric cars are great, unless you can’t find a place to charge them. And when you finally do find a place and it ends up like this… yikes.
“Heard a loud noise coming from my apartment bedroom. The entire ceiling suddenly collapsed…”

Don’t you just love it when your whole ceiling collapses for no reason? Yeah, me neither. Hopefully it won’t take too long to fix.
“Mac and cheese became a side-venting volcano of cheesy lava.”

This really sucks, but at least the microwave can be cleaned. Still, that doesn’t mean the mac and cheese is going to taste as good, what with all the cheese missing.
“Just had to break into my house.”

I feel bad for OP because not only did their key break, but they got roasted in the comments for having such old locks. At least this is a good excuse to modernize a little.
“My impacted wisdom teeth. Top ones already removed.”

Getting your wisdom teeth taken out is no fun at all. Having to get them taken out through more than one procedure? I’d be so tempted to just let them ruin my jaw.
“I really needed to get some cash.”

This is as good a sign as any that you probably shouldn’t be carrying cash in that neighborhood anyway. Hopefully the next ATM isn’t too far away from where this one is.
“A single LED colour broke on my computer fan.”

The worst part about this is the fact that OP now has to take the fan out and replace it, which is just a lot of time and money.
“This happened…”

This is probably worse than when you get something stuck in its spot in a vending machine, because this would’ve gotten your hopes up. I guess a bag of chips wasn’t in the cards for OP today…
“I fractured a bone in my back the week before vacation.”

There’s never a good time to break a bone, but the worst time is absolutely when you’re about to go on vacation. Think of all the stuff you had planned that you can’t do now…
“Got a milkshake and this is the straw they gave me.”

Nothing like getting a milkshake and then not being able to have it because your straw is defective. Here’s hoping OP was able to get one that actually worked.
“Got stuck.”

Whenever I see something like this, my first thought is to hope no one got hurt. My second thought is to think about the poor sap who has to go and talk to the supervisor about it.
“If you came through Louisville a couple hours ago, you left something behind.”

Oh man, now that’s definitely something you don’t want to leave in the middle of the road. Are you even allowed to stop to hitch it back onto your car?
“I am getting married tomorrow. Celebration will be at our Home. This is the street right in front of my house today.”

If only you could be like, “hey, I’m getting married tomorrow could you move,” and they’d be like, “oh dang, sure.” If only…
