15+ Mildly infuriating brothers and sisters who can't stop bugging their siblings: 'My lil brother's phone screen has TikTok burned in'

No one knows how to push your buttons like your very own siblings! Family members are with you from the very start. You've known your siblings since the day you (or they) were born. So it just makes sense that they'd know exactly what you like and dislike! 

If you and your siblings ever had to share a bathroom or a bedroom, you know that even the smallest things can start an argument. One person shared the way that their sister leaves the bathroom looking: she's clearly a makeup lover, because she left her supplies scattered in the sink! That must be annoying for her sibling, who presumably has to move handfuls of beauty supplies just to wash their hands. 

Another person shared their headphones with their "gym rat" bro. How nice of them: he could listen to his tunes while running or lifting some weights. Too bad he returned them in an unusable shape! The headphones were totally demolished. Not cool bro, not cool. 

Check out a bunch of sibling drama below! And speaking of gym rats, read about the folks who worked out in some hilariously strange ways, like one person who was spotted "using a leg press with their arms."
