Some people are just irritating

We had an interesting afternoon. We got home from work and one of Stirling's toddler friends was out playing with the older neighbor kids. We stopped to play, and as soon as I let the kids use Stirling's toys, all heck broke loose. These two older kids don't have many toys, and when they play with ours they get greedy and wild. Anyway, they were pushing our little friend Nathan on the ride-on dump truck and were too rough and ran over his toes his foot got pretty scraped up and started bleeding. After I told them several times that they were too big to be on our toys, they started playing with the T-ball set. The little girl wasn't watching and blasted Stirling right in the lip with the bat. It took a pretty big chunk out of his lip and he started screaming. It bled for over 30 minutes even with Stirling eating popsicles the whole time. I almost took him to the urgent care. While I was holding Stirling with a bloody lip, the kids started pushing Nathan on the dump truck again, this time at full running speed and pushing him down the sidewalk. So there was this little one year old careening along on a dump truck faster than the moms could run. My heart just about leapt out of my chest. Nathan's mom Felicia and I aren't thrilled about having these kids around. Especially since their dad was standing there the whole time not saying much of anything, just kicking our ball around and talking on his cell phone. I discipline kids all day, and I really don't want to do it when I get home. I was irritated. I know accidents happen when kids are playing, but this dad never corrects his children or follows through on his threats. I am still irritated.
