Clarification: I'm not really blonde... :) The top layer of my hair always lightens over the summer months. I like it so I don't try to prevent it or cover it. Anyhow, I guess one of those lighter strands fell on the keyboard and somehow slipped down into keys, too light to be very noticable.
Anyhow, thats my disclaimer.... not really blonde it just sounds as though I might be the model for those awful Blonde jokes at times. :)
