DS is 17 in November and about to start a levels. To cut a long story short last night he told me he was going out with some friends (technically true). He wasn’t back until about half 11 but went straight to bed so I didn’t get a chance to talk to him. It turns out he was in the pub last night with a group of other underage friends I was told this by a friend who’s (adult) son also happened to be there. I am very disappointed in DS what he did was both illegal and stupid. Aibu to ask how to punish him for this?
