My 17 year old son is quite a reasonable well adjusted teenager but he doesn't like to tell me where he's going at night. If he's going to a party he's never exact about the address or name. I give him a lot of trust but last week he was out in another town to gone 3am with his mobile switched off. Big question - am I being unreasonable wanting him to - let me know where he is / whether he's in for tea / be contactable. He knows I'm not checking up on him I just worry about what happens if I need to contact him or if there's an accident. He's one of 4 sons and we have had life threatening illnesses and accidents etc in the past so am I a nervous Mum? Single Mum, divorced, but on good terms with Dad.
