Only one is a teenager - he's 18, and my older son turned 21 yesterday (!) My perennial worry is that they both seem to have trouble making and keeping friends. My older boy seems to be beginning to realise this for himself, or at least has mentioned it for the first time; the younger one is extremely shy and seems unwilling to try and make contact. Can I help them now? Where did I go wrong? We always had friends to tea and play dates when they were little, but once they hit secondary school they never had anyone round at all!
