Depends where you live.
If it is a Coronation St environment, houses back to back, terraced, kids outside shouting and screaming, kicking a football against the walls, washing hanging on the lines........then it would seem normal.
Complain and your likely to get a Glasgow Kiss.
if on the other hand, the area has mostly detached residences with at least 4*4 's, Mercs or BMW in the drive, kids indoors doing their homework and someone decides to mow the lawn.....yes, that is unreasonable and yes i would complain.
Difference is between "nice people" and "common folk".....you understand.
