Silence, I don’t like to be talked to in the bathroom and I don’t like to talk. Plus I know it’s infuriating to get nothing back when you knock. But if the door is locked go somewhere else or wait, not my problem.

If the door is locked then sure.  But sometimes it's not and I push the door open and the person inside starts freaking out because I'm walking in on them when they didn't acknowledge my nock.
