i just had a brilliant interaction with someone i work with. we had a fabulous conversation about his son and how they finally bonded during their latest time together [he is a noncustodial parent] and my daughter and how her tiny little self is kicking my ass, and about llamas and work and caffeine and this and that and the other, and while it doesn't sound like much, it really was wonderful. i was charming and funny and never at a loss for words and yet, about five minutes into it, even though i was thoroughly enjoying myself, i started thinking, "okay, time to go."
