If you became invisible for a day, what would you do?

Kind of on the same topic! I put a wireless camera in my room to look outside my window which faced the front of my house. It was paired to my phone so when my dumb cat would jump in front of the window, his reflection would pick up and I'd get a notification about movement. Anyway, one day it was pretty late when I got a notification so I checked the live feed and saw my dumb cat there, but the cam also picked up sound. I could hear my little sister and my dad talking about me, things I didn't expect them to say about me. I know they were confiding in each other but I couldn't help but listen. It stung but I could never bring it up to them. Guess the moral is, I would have thought I'd listen to what other people had to say, but in the end it usually just ends up being painful
