I don't know if I'm posting this in the right section but I hope I am.
Over the past few weeks I have noticed something about my son that is worrying me a little bit. He's nearly 18 yrs old.
I've been in the car driving him somewhere and when he gets out I noticed a damp patch on the seat. I shrugged it off the first time I saw it but I've seen it a few times now. I saw it again this evening when he got out of the car. I'm trying to think logically what it could be but of course there's all sorts going through my mind.
Has anyone any ideas what might be causing it?
