about last night...

Used as the opening to a conversation regarding the events of the previous evening, often involving an unpleasant or embarrassing topic. So, about last night... I was a little out of control. I guess I had too much to drink. Well, about last night… things must have gotten a bit out of hand at the party. I guess that's all you can really say when you wake up on the floor and don't remember most of what happened. A: "So, about last night…." B: "Ugh, do we really have to talk about all of that right now?"
