It's annoying when:

1. Your cookie doesn't fit into a glass of milk
2. Your hot pocket starts spewing out its filling.
3. When your belt rings get hooked on to door handles.
4. Wires and cables get entangled with the legs of tables/chairs
5. HANG freakin NAILS
6. When drink cartons don't open the way you want.
7. Pencil lead refuse to cooperate.
8. Charger ends up covering other sockets.

UGH. The most frustrating things ever.
