To me, the blues is an infection. I don't think it's necessarily a melancholy thing; the blues can be really positive and I think I think anyone and everyone can have a place for the blues. It need not always a woeful, sorrowful thing. It's more reflective; it reminds you to feel.
A friend of my mom's was a casting director so, really as kind of a lark, I had a couple of acting jobs that had just enough exposure to give me the option to continue if I wanted to. I followed through with it.
