Silent retreat

You've had a night out, you got drunk and went home with someone to their place. Sex was had and you went to sleep happy, satisfied and wasted.

You wake up the next day and suddenly realise what you did. Full of regret (for whatever reason), you then try to make a silent retreat so last night's partner doesn't notice you leaving and ask any awkward questions (like "can I call you?")

Henry: It felt so right at the time, me and Sarah had this huge argument, this girl was all over me and pretty soon we're back at her place.

Eddie: Oh geez...
Henry: Yeah. I wake up next morning to find myself next to this complete stranger lying asleep and text messages from Sarah telling me how sorry she is.
Eddie: What did you do?
Henry: Make a silent retreat. Last thing I needed was her asking me for my number.
