My 4yo son accidentally threw a toy into next doors garden whilst playing with his brother who is 2 (almost 3) on their trampoline. Dh said he'd go round to ask got it back, I said to take DS so he can apologise etc. When they got back my Dh said how he'd spoken to the woman and he explained that DS had accidentally thrown toy over when on the trampoline and said something like "yes, we can hear the trampoline" so Dh says "oh, is it bothering you" to which she replied "well we can hear it". Aibu to be upset/annoyed? We moved in only 6 months ago and the neighbours have clearly lived in their house so long time (old retired couple) so I feel awkward. Compared to where we used to live, it is wonderfully quiet... A big reason I wanted to move here. But my children make noise, they're 2 & 4 and They love playing out in our back garden on the slide, little play house, riding their bikes and bouncing on their trampoline. They don't go on it at unsociable hours-they have a pretty strict bedtime routine, so the latest they are out there is 5:30pm, in bed at 7:30. My youngest is a screamer (slow developer, possible autism) and will scream when both happy and sad but my 4yo is such a polite little boy and us very well behaved. Now I feel stressed about letting them play and I'm fretting over any noises they make.. Which is just crazy. It's an estate full of family homes! Aibu?
