DD was playing in the garden tonight and our neighbour and some boys were smoking weed. I've smelt it many times before but hadn't realised that's where it was coming from - she has a 2 year old who was also out in the garden so hadn't suspected her at all. If it wasn't for her having a child there, and my children having to breath the smoke in if they want to play in their own garden, I'd mind my own business but now I'm thinking of reporting her to our joint landlord. AIBU?
