My Dad called me "Maggie." He liked the song 'Maggie May,' by Rod Stewart. The lyrics aren't especially fitting to give a kid this nickname, but he always called me that.
My other nickname is a play on my first name that my aunt, who is also my Godmother, gave me when I was a baby. In this house it's what everyone calls me. My sister calls me by the first syllable of my name, which I don't like, but she's the only one who does so I put up with it.
