School ends here next week but early releases, field days and test days mean that the neighborhood already has a summer-vacation vibe.

Exhibit A is the first lemonade stand of the season, featuring an enterprising bunch of school-aged kids. Its ringleader waves a sign half as big as he is, and practically flags down the cars on the street. The other day I saw him trying to stop a school bus.

When I drove by on my way to walk Monday, I slowed the sedan, and realized I’d left my wallet at home.

“Sorry,” I said. “I don’t have any money.”

“No problem,” he said. “We take Venmo.”

Such is life in the elementary-school fast lane. I can’t wait to see what summer has in store.

(Another sign of summer.)
