This happened to me a couple of weeks ago. Neighbor DCD came to pick up his kid just as we were headed outside to play. DCB didn't want to leave, so they, along with the older brother ended up staying for a bit. It wasn't too bad, but then DCD said he had to pop home to talk to a plumber who just arrived. Thirty minutes later, they were still there! The siblings are completely out of control and I was so frazzled. We ended up going in to the backyard so I wouldn't have to worry about either of them running on the road. SO not cool.
