Diana, at 3 and 5 there's not much of use they can do. ;(
They were here at 8:30 this morning already.
I had left a leash hanging on the railing outside last night because Moses peed on it, so I didn't want to bring it in. The kids decided to bring it in "for me" so I made a big deal out of the fact that it had been covered in dog pee hoping to gross them out and sent them home. It didn't seem to bother them at all.
It's not like our houses are terribly close... if this were a city block, there'd likely be 3 other houses between ours! They just don't know enough to stay away.
I'm probably the only adult they see on a regular basis who doesn't yell and swear at them, but if they keep this up that too might change. The yelling part anyway...
