Good stuff from Mary Anne about how to leave room for a polite no when flirting or otherwise expressing interest in someone.
It's all stuff that I theoretically know, but I have unfortunately behaved badly in this regard a couple of times over the years. Unintentionally, but that doesn't make it better or easier for the other person.
I especially like M's side note saying that it's “easier to flirt lightly if you do it early” and the rest of that paragraph.
There is lots more I'd like to say on these subjects, but am only semi-awake, and really ought to go start the day. But I wish that I had read this entry of M's back in high school.
