Oh yeah I know Clark is really, really chill about Bruce that he even doesn't mind if he were to sneak in his room while he's asleep, but I just find it funny that Bruce while being a person who is really private about his stuff tends to invade other people's privacy. I think the only time Clark got mad at him is when he was spying on him and Lois with his binoculars but that's it.
Usually, they come in for inane purposes like spare changes of clothes they keep in my room for some reason or to borrow my deodorant or cologne (when they are running out of the stuff) and most of the time won't leave until I tell them to.
Oh yeah I can't tell my mom to leave or she'll get mad at me for like a week and will take everything against me or make it about how I need to get a good job or whatever I did wrong in that day. Oh and it sucks what your younger sister did, I don't have younger siblings but I do have younger cousins and if I don't watch their hands they can do just about everything (last time they were here I found bubblegum plastered on the side of CPU).
