I noticed some behavior of mine at work today that drives me round the bend and I have no idea why I do it. I say 'thank you' when it's me doing something for someone else. Maybe they think English is my second language because I have yet to be corrected. Example, I'll do a favor for someone or print something out and hand it to them and say 'all set? okay, thank you!' what? i may as well work at a drive thru fast food place with that attitude.
