Neighbours in garden.

[KindergartenKop]

We live in a semi detached house with a small garden in London. It's hot so we've been sleeping with the windows open. Next door but one is a student house. Last night and at least once this week they've been out in the garden talking and woken us up. This has been after 10:30pm because that's when we go to bed and we definitely have been woken from sleep rather than not able to get to sleep.
Aibu to have a chat with them? Fwiw I don't let my kids play in the garden until 9am so as not to wake child free neighbours, I feel they are not being considerate of our sleep.

Oh and in a new development of summer misery, someone somewhere in the vicinity is playing really loud thump-thump music. At 2pm in the afternoon. Won't keep me awake, obviously, but FFS don't people realise that's fuckwittery. It's probably some distance away (ie not right next door, can't even identify where exactly it's coming from) but noise carries and it must be awful for the people right next door. And for 100 other households within earshot. Oh the joys of summer fucking holidays and working from home.

I hate people sometimes, I really do.
