Hi there! Well, it's actually tied into when I got my cutiemark, I knew I wanted to paint, but nothing I tried was working, I wasn't dexterous with my hooves, and I was struggling to use my mouth like some of the other ponies could. I was in art class when I looked up and saw this sign that said we couldn't make any mess, I stared at it, frozen in place as I knew what I wanted to do.
Something had awoken in me, and as I dumped paint over myself and used my tail as a brush, I was overcome with this desire to paint! When I was caught, the teacher was about to tell me off when they noticed I had my cutiemark, it was my destiny to paint!
