"Date 101" is, I belive,a US way of saying Dating classes since 101 is the nunber of the class room (I am really very unsure about this, I use it to descrive the way things are "date 101" is dating, "sleeping 103" is not paying atection, and so on....)
As for personal, I mean personal, like "I am going to take a bath righ now" and stuff like that.
There is nothing wrong about being friendly in here, but somethings are too personal and people can get the wrong ideas about the other side meaning (This is not, I belive, a dating message board, but things like that happen).
