Am at the town large play-park with DS’s 11 and 8. They and some other kids keep looking hopefully at the basket swing but no one can go on it as a grown woman is laid stretched out sunbathing on it. She glances at the kids but doesn’t move. The kids are too polite to say anything but I think she should flipping well make way. Sign on the entrance says equipment for up to age 15. Would IBU to tell her to shift herself?
