Right, those kids are probably friendly.

Ethan waits for the crossing light and crosses the street (He notices he is the only one using the crossing lights, but shrugs it off).

He notices some young women standing in a group talking. They look old enough, so they might be someone to talk too. And maybe get to know better.

On the other side of the park a young woman is pushing a small girl in a swing. They both are cute enough, but is that the girl's mom? Probably not, the young woman doesn't look that old. But Ethan does not want to start out with a ready made family.
