In our instance, Matthew will willingly go to Scott's soccer games because he likes being outside. That being said, it is extremely difficult to "control" him at these games if Omri isn't there. Our local soccer complex will ask us to leave if we have Omri with us. I'm not quite sure how to go about fighting this attitude even though I know we have the ADA on our sides. It's not like we have an attorney on retainer that we can call & ask them to "go to bat" for us. (or would that be Go to goal since it's soccer?) Anyway, imagine the dirty looks you would get if your child were to run off screaming from you. People instantly believe you are beating them or worse...there is no sympathy...no help except from the people you know & they ARE willing to help. We consider them our angels. Thankfully, all of our soccer parents this season have fallen into that category. If Matthew disappears, they'll notice before we do & ask if we know where he's going or why. If we don't, one will help us try to find him.
Anyway, if you read my blog at all, you know how we live, and there's no reason to beat a dead horse to death, but I do think you'll enjoy reading the above link.
