What “signal” that someone thought you missed did you absolutely NOT miss?

A friend of mine always talks about a time that a group of us were hanging out at a party on a bed and gradually everyone left leaving me with this girl and they “totally planned it so we could make out” but I also totally realised what was happening and got the fuck out of there…

I didn’t miss anything, I wasn’t up for it, I just didn’t need to hurt any feelings.
