Nok arrives at our table, beaming her angelic smile over a plateful of volcano rolls. She sets it down, then brings us more Sapporo. How old could she be? 19? Yet so independent, so brave, here all by herself. We are going to Thailand next week. This dinner is anticipation. "You make me miss my country," says Nok, giggling and struggling for words. "What hotel are you staying in?" Two days later. Bangkok. The telephone rings. Nok's friend. In case we need anything. Why stick to Broward and Palm Beach? Nok is the sweetest waitress in the wooorrrllllldd!
