    "content": "Irene, I would like to introduce you to Gideon Park.\n\nHe directs a high school band and is on sabbatical this year. He plays piano at parties if he is asked twice; I would ask twice. I think the two of you would enjoy a long supper and not notice the time.\n\nSay yes if you would like to meet him. If not, say no, thank you, and that is the end of it. He will not learn who said what.\n\nNadia"
