It's no different than people who like to talk about their kids. I could have told you about the art work on my refrigerator that my kid drew in third grade, except that would be a lie because I don't have any kids. My legacy, such as it is, is my work, and my little stuffed lobster is no less a token of that than the third grade art project on the refrigerator would be if I had one of those. I'm sorry if that offended you. Talking about one's children is generally considered a socially acceptable thing to do. A little tacky perhaps, but not something that merits a snide response.
