We all do sneaky things; creating fake Insta accounts to stalk our exes, ordering an extra large pizza for yourself and have it delivered to the side door so you don't have to share, warming up food in the microwave at 3 am and waiting to stop the time at 0:01 so you don't wake up your roommates...again.
See, these are all normal, common sneaky behaviors. These people, however, take it up a notch.
