Bob,
As it turned out, at the very same restaurant as I had the Margaritas, last night my grand-daughter had a once in a lifetime opportunity to spend several hours, at dinner, with her favorite singer/performer, Serena Gomez. My son tells me that they bonded immediately and had a great time, as did my son and daughter-in-law. Serena even gave my grand-daughter some "big sister" advice: "Listen to your parents". I even got the latest scuttlebut on Serena's on-again, off-again relationship with Justin Bieber, but my lips are sealed on this. I have been receiving photos of the occasion, including the one below.
