If a cop was standing right behind you would you look back at them and laugh nervously?

Most likely, I would shake the officer's hand and thank them for their service.

No, lol. This happened more than once and I didn't do anything. Still not a pleasant feeling tbh.

Id just ignore that they wer there. They dont make me nervous. Im not a criminal

No but why are they in my house?

No Id try to pretend they weren't there

I’d say are you finally arresting me jeeeez I’ve tried giving myself to yous 😝

No, I would just ignore the fact that he/she was there.
