My son worries me. He hasn't got many friends so when he gets invited out by work or uni friends he drops everything to go. Of course I have no issue with that. But he never comes home when the rest of them all leave to go home. Instead he wanders about trying to hook up with strangers and has even asked and stayed overnight at strangers houses. When he lived away from home he would drink a lot on nights out. So much so that he'd end up in hospital with alcohol poisoning. None of his so called "friends" made sure he was OK, instead they left him lying in the street till an ambulance picked him up. I'm so concerned with his destructive behaviour. I've tried to explain to him that what he's doing is dangerous and affects our family. He really doesn't care, he just wants to have "fun"! Am I really being unreasonable?
