This. ^ Some people do shift work too. No-one wants to be disturbed by someone's screechy, hyperactive, wailing children on a trampoline in the garden, at ANYtime, (many who are there because their parents can't be arsed to pay them attention, and parent them.)
No need whatsoever for children to be in the garden screaming at 7am! Or at any time of the day for that matter. And people in the house after 7pm, are not making anywhere near the amount of noise as the screeching kids! So that analogy is moot.
