Best chat-up line evah: "hey girl say good morning to mister boner !"
I am too clutterbrained to always remember saying good-morning. bad thing is when I only occasionally say good morning people tend to think, the times I dont say it I dont like them or am angry with them or want to proof a point. You cant imagine how much crap people do interprete in a simple societal norm like that.
I tend to say when I enter a room "Good morning, good miday, good evening and if we dont see each other again: good night"
