Talk to Them and BE FIRM

My kids are grown so they don't play with my neighbors'.  The neighbor probably also baby-sit for someone else so we got these three or four boys always wanted to play on or near my driveway.  After one time they pushed little baby carts down my driveway i could not take it anymore.  I went over and told the kids that it was very dangerous and they should not play here.  The parents dashed out thinking I mis-treated their kids.  I told them that this was my property and I did not want to be resposible if they got hurt, for their own benefit.  Now they stay away.  Of course my neighbor and I are no longer "friends".  Who the f*ck cares.
