People who drive slow in the fast lane
Nothing boils my blood more than people who cruise at 50 in the passing lane. If you're not passing, MOVE OVER! It's not that complicated.
Wet socks
Stepping in a puddle with socks on is a special kind of torture. The wet fabric clinging to your skin, the squishing sound when you walk, the cold... it's unbearable.
Automatic updates that restart your computer
Was in the middle of an important project when Windows decided it was the PERFECT time to install updates and restart. No warning, just 'updating, don't turn off'. I lost an hour of work. I HATE THIS SO MUCH.
People who talk during movies
I paid $15 to hear the movie, not your commentary on every scene. Why even go to a theater if you're going to treat it like your living room?
Pineapple on pizza
It's a culinary abomination. The sweet, acidic flavor completely ruins the savory perfection of pizza. It's not 'trendy' or 'bold' - it's just wrong. Fight me.
