Stupid woman downstairs smoking weed every night making my flat stink, I’ve complained so many times by its driving me mad now so worried about Mia more than anything .... I do everything I can but I don’t think it’s safe for Mia to live here with that all the time going on (it’s not just a smell, it’s the effect of the stuff also that’s not healthy!!) I’ll complain every day if I have too.... some people might think I’m over reacting but I don’t want my daughter around it 😩😥
