Musical Chairs.

I hate it when I get up off a chair to pee, for instance, and when I come back someone is sitting where I was sat.

I HATE THAT!

What the hell on earth was wrong with the chair they were already sat in? Because unless they were privy to the information that the toilet had the ability to swallow people whole, they knew I was coming back, right?

Is this just a quirk of mine or do other people find this as annoying as I do?

It's like putting on someone's underwear when they take them off.

It's just rude, is what it is. Rude.
