Do I have to pick just one thing??
I'm a stress case. I stress about a lot of things. Maybe this something isn't what stresses me out, but it does get under my nerves and causes some anger.
Being late. And not overly late for things, but I'm talking 2 - 5 minutes late. Drives me crazy!! I am always 5 - 15 minutes early for everything. Movies? At LEAST 15 - 20. That way I can get my tickets, popcorn, a seat, and a bathroom break.
