I can’t think of a good enough reason to warrant it.
We have a new family move next door.
A family, mum, dad two kids, boy and a girl both under 7. They are Indian, and we have met the grandparents on one side, who came round to introduce the family, as they don’t speak great English. I’m mentioning this in case there is a cultural reason/festival I’m ignorant of - not because I’m a daily mail reading gammon head 🙃.
Anyway. Over the last couple of weeks, we’ve been woken up by the entire family in the front garden, talking loudly at like 11pm -12.30am. We were a bit
as the kids were out there too, and it seemed a bit late for them to be out, but it’s school holidays. We have an 18 month old, so not sure on what’s acceptable on older kids bedtimes.
However over the last three nights, dh has been woken up by them, including the kids at around 3.30am 
Am I being ott or is this really not on? I did wonder if one or both of the parents work weird hours, but even if they did it seems a bit much to let the kids keep the same anti social hours
