They moved in on Saturday, and didn’t say hi or respond to us smiling and waving.
Sunday they had 3 screaming rows and my dc with ASD was terrified, so I explained moving was stressful etc.
They’ve also left their tap running since yesterday morning, which is driving me insane as it’s making me need the loo!
Then yesterday my dc asks me what that noise is at 6.30pm, they are only having sex in the kitchen! Theirs not mine lol.
So I’ve just been doing a bit of maths with dc, we HE, and they are at it again!
Now I realise it’s their house they can have sex whenever and wherever but omg, how do I hide this racket from my kids? Or what do I do?
They know what sex is due to sex ed, the minimal science part... but this is still very awkward. Thankfully the guy doesn’t last long. 
They must hear us, thin walls, so surely they know we can hear them?
We have a young couple the other side, and we never hear them, very respectful of us and us them.
I’d die of embarrassment... I’m sure I’m BU but I never realised I was such a prude and I also never thought of how to hide sex noises in the middle of the day from my kids.
