Where to begin? There's so many!
I hate it when my dog buries her greasy steak bones in the laundry pile and wrecks my best shirt.
I hate it when anyone leaves the milk out on the counter. Or the mayo. Germs ya know!
I hate bagpipes. I once heard, "Bagpipes are a joke the Irish played on the Scottish years ago ... and they still haven't got it". We have a bagpipe player down by the Inner Harbour ... I'm always tempted to drive up on the sidewalk and end the infernal racket!
I hate clowns. Even before I read Stephen King's "It". They're creepy!
Trolls. I hate forum trolls. People looking to piss others off for no apparent reason. (Only really started hating them since I became a moderator!)
Feet. I can't stand anyone to put bare feet near me when I'm eating in front of the TV. Even the dog's feet. Ick.
Wrinkly bed sheets ... bottom has gotta be nice and tucked in, top has to be untucked but no wrinkles. Princess and the pea syndrome.
