Our next-door neighbors have a daughter (19F) who was sunbathing in her backyard which is separated from ours with a fence. Apparently after swimming she started sunbathing topless in her backyard.

I found my son perched by a small window up in the attic and I asked him what he was looking at. He just looked at me and said "nothing" but I went over and saw what the neighbors' daughter was doing. I thought the worst and my suspicion was confirmed when I checked his pockets and found some crumped up tissues.

I grounded him for the weekend which meant he had to miss a sleepover at his friend's place. I explained to him plainly that his actions were disgusting and that I'm not brushing it off just because he's a teenager.

My husband said I'm overreacting. He said our son was in the wrong but that he is going through puberty and that I went with too harsh a response to him just "being a boy". I completely disagree. Just because he’s a teenage boy doesn’t mean he gets a free pass to do that. My son was sad about missing the sleepover but he seems to understand how wrong his actions are and told me he won't do anything like that again.

AITA here?
