"Oh well... Next time I'm putting up a fence."

Plant a bunch of these.

Or these:

The problem is, if he planted those things, his neighbor (after pushing his own kid into them) would sue him. Maybe he should send his neighbor stories like this one of rotten little brats anonymously in the mail so he gets a clue.

He can address them to "owner of rotten brat" or something like that.
