I'm fair haired and in my younger days I wore my hair at waist length. I discovered after we left school that people had been calling me "Goldilocks" behind my back for years. I found this fairly amusing given the things I was called to my face during my school days & I actually rather liked the moniker. I use it as my identity on a number of internet forums, and spelled it with an X because the correct spelling was already taken on the first one I joined, and I hoped it might stop people mistaking me for a girl (it hasn't).
<--That's my hero: Dr Teeth, leader of The Electric Mayhem. I was bored of the picture of the actual me I've been using since I joined Stafford Forum.
