My neighbour (terraced houses) has (I think) started seeing somebody. She's a single mum, middle aged, I'm pleased for her. Our relationship is cordial - we can say hello on the street and I have her mobile number but never socialised or anything.
The issue is she is (I think) started having sex late every single night. The sound is a squeaking mattress and a thumping headboard, along the wall where our bed sits. It lasts about fifteen minutes. I can't think what else it could be.
It varies from between 23:30 to 01:30 (last night) and it is loud enough to wake me up.
I don't know what to do about it. I'm losing sleep but I cringe at the thought of saying anything. I floated the idea of a concerned text about hearing her washing machine/boiler/pipe noises late at night which would let her know I can hear her but my DP thinks this is a mental course of action and I have to say I agree.
I've started dreading going to bed, though. Any suggestions?
