I am in the minority, but I save things for the next session, even when they are going round and round in my head. This happened when I noticed that my T changed my DX code on my forms. It was killing me, but I waited the week between sessions. In that time I was able to run through a lot of different scenarios and come to peace with even the worst one, and it turned out to be an innocuous error in any case. I just feel too uncomfortable contacting T outside of sessions. It's not my way, and not his, either--we've never even discussed the possibility.
