IHIW you come home from a sleepover and you're really tired and people keep bugging you about what you did.
IHIW a person you're sitting next to at a meal is reading a book or something and is completely oblivious to the fact that they are chewing really loudly and sound like this, "CHOMP. CHOMP. SLURP. GULP."
Honestly, people in general annoy me, unless I'm not feeling slightly grumpy. Manners, people!!
