Just want to canvass opinion to see if IABU. DS (14) come home and said there's a party on Sat night for X's birthday (he'll be 15). This is first "proper" house party my DS has been invited to. I do not know the other boy and there appears to be only 1 other boy going that I have met. AIBU to want to check things out with the mother of the host - I want to be sure there will be adult supervision primarily, and that she is aware party is taking place, and really just want to check out the lie of the land IYSWIM. I knew first house party was likely to arise this year but could have done with a bit longer before having to face it - I suppose my main concerns are general silliness leading to daft/dangerous activities/alcohol/poss. drugs. I know I have to learn to "let go" within reasonable parameters but am not sure what is reasonable at this point! Any wise words of advice/views very welcome (am expecting a mixture of views, I think, but will at least help me to think it all through).
