I dislike trendy names because a name is
NOT like fashion. That is, you can change your clothing, but your name is stuck with you for life. You'd feel awfully silly if you had to walk around wearing clothes from the 70's for your entire life, wouldn't you? It's the same thing with names.
Have you ever noticed how you can guess the age of most people named
Susan,
Linda, and
Amanda? That's because their names were incredibly trendy. They were pretty and fresh when they were given to them but now they're just a burden, and you rarely see babies with those names.
