This isn't something I've ever seen before: when I went to parks, the other parents stayed out of the way, and my mom had to take care of us: especially hard since at the time, she was typically watching somewhere between 5 to 8 kids.
Is this normal? Do most neighborhood parks have parents all over them helping out all the kids?
Alicia even got to help some lady who was playing tennis: she tossed balls to her to help her practice her swing. (I think she was a Brit of some kind: definite accent, but I don't have the experience to tell where.)
