you know a lot of these teens have been abandoned, beaten, molested and are immature, if they want to hang on the swing, I don’t have an issue with it. If they are picking on kids, they need to leave.
Perhaps in Hollywood ... but at our playground, they are children who live in the subdivision and are simply being inconsiderate. We have suitable swings for all the children (and adults - I weigh less than my teenagers).
If older children break the baby swings, then babies can’t swing, and the residents have to pay for repairs.
