I don't know what chalkboard board guy is referencing here, but I photographed it because it reminded me of a conversation I once had with my cousin, L.
Timeline: 1992, on holiday in Madeira. We are the youngest guests in our hotel by about 25 years. We get asked out by 2 waiters and, after checking with our Rep that we'll be okay ("They'll treat you like their Mamas"), we go. And have a good time.
As we are getting ready for bed, my cousin says, "Oh, I forget to tell you ... waiter A said that he loves me. But I knew he was lying."
"How did you know?" asks me, once I've stopped laughing hysterically.
"His lips were moving."
