My son has displayed signs of disturbing behavior,he is 24,he has left excrement on my coffee table while drinking,and could not give me an explanation of why he did this,this is not the first time.I am worried he might need some help etc and don't know what to do, help:confused:

You are going to have to get him some help, leaving excrement on anything belonging to a relative (or anybody else for that matter) is really disturbing behavior. Was this coffee table cherished by you, and did your son know that, because it could be directed at you in a sublimal way.

He has a problem this is beyond disturbing into seroius worrry situation.

If he is drinking to this point, first there appears to be a seroius drinking problem, and this appears to be a serious mental issue also.
He is in need of counseling services
