What do you think of me telling a kid to not peep in the bathroom?
I think that is acceptable. Does it make you feel bad to have a kid peep into the bathroom?
It's fucking disgusting and gross and I hate it.
It's wrong and inappropriate behavior to peep on others while they use the bathroom and it's good that you are telling the kid not to do it. If the kid continues to peep, it would be a good idea to contact someone with authority such as a teacher about what is going on as the kid may need an intervention over his behavior.
WTF I was only joking.
Whether you were joking or serious, it's good to let kids know that peeping into a restroom when someone is using it is wrong.
