Hey SC, you and I both have sons around the same age, so I know the fear you have for him. My C is concerned about my son also. He is very depressed and I am afraid because I have alcoholism in my family.

My son has always been "straight edge" - totally against drinking and drugs. But I saw on his flickr page (its a photography site) that he questioned whether it was worth it to continue to be edge. That concerns me.

I also saw some things on myspace. The thing is, as teenagers, I think they all embelish a lot on there. Not to say you shouldnt been concerned, but I know in my son's case, he has stretched the truth a bit.

I am not telling him at the moment what I have read. He would be very angry. And like your son, my son is a good kid.

I think that you having had numerous conversations with your son and having him know where you stand on things is very important.
And keeping the lines of communication open.

Just keep an eye out and keep listening and watching.
