Ok. This happened a few months ago. My friends and I had a weekend hanging out at our friends house out of town. We were sitting there and it started to get late. We all slept in different rooms, and I slept on the couch. I was still up, texting one of my friends, and I noticed my friends phone was right there, being charged. I know it was none of my business, but I decided to check out his phone, just out of curiosity. Well, I ended up seeing some pictures of his girlfriend, completely nude. I felt weird about it, because i'm also friends with her. I then put the phone down, and went to sleep. Should I tell my friend about it, or just keep it hush like I have been?
