I didn't hear any mention of Alice W. taking a moment to find the first guy, apologize, explain the situation, etc. Doesn't sound like they have any past history either, to make a moment like that an anomaly in an otherwise agreeable acquaintance. There was a lady that ended up on my do-not-ask list for a worse behavior. At a later date, she asked me to dance, and thereby removed herself from my do-not-ask list. There's a lot of extra ladies where I dance. I don't assume anyone is going to "shrug off" my behavior. And while I won't go home and fume about it, I will focus my attention on others.
