I'm not saying you can judge the quality of your friendship by the memes your friend tags you in, but you gotta admit that it's a good way to gauge whether they get you or not.
If they keep bringing a bunch of polka memes to you and that's not your jam at all, it's a warning sign. And yes, polka memes are probably a thing.
Whereas if they show you something like these, they're probably riding the right wave.
