She sometimes smells like poop. Its never bad just enough to notice from time to time if she is standing really and for a while I thought it was my imagination until I slept at her house the first time. I have made comments a few time and even asked her if she had an accident but she just says no and changes the subject. None of my other friends say anything so I haven't worried about it for a while but yesterday I heard guys talking about her at the bus stop. The 2 guys talking were caught taking pictures up girl's uniforms and were telling the three new guys that she pooped her pants. They told them they think she does it every because every time they took pictures of her she had. I haven't asked her about it or told her I know because of her reaction before but should I tell her other people are talking about her or just keep that part to myself?
