I had a meeting near to my son's school yesterday so gave him a lift in (he normally takes the train). I needed to walk past the entrance to school to get where I was going but my son didn't want to walk with me in case anyone saw us. I wasn't going to kiss him goodbye or even hug him but he refused to walk with me and couldn't understand why I got upset. AIBU to feel really sad about this? He is 16.
