It doesn't take much. Just two kids. Pint sized. Eager. Sitting at a folding table in the open air market in Gdansk. The sign, in English no less, says LEMONADE.

Seconds later, I'm sipping some. Not too sour. Not too sweet. Just right. I tip them the price of another. They put the coins in a cup.

On the walk home, my mood turned from rainy thoughts to summer ones again. Give me a lemonade stand or a guy on a saxophone any day. I cannot resist. I'm won over to happiness.
