Burn Baby Burn!

So I'm an adult. 29 years old. I've been dressing myself and doing my own hair for years now. Never had many technical difficulities. Thursday morning I decided to do my hair for work. No, this does not happen everyday. There are days when ponytails and headbands are my very best friend. But I got up somewhere close to on-time and thought I'd wash and blow-dry my hair. I was using my big round brush just blow-drying away when I started smelling burning hair. I thought this was very strange as this normally doesn't happen. I stop the dryer and pull the brush from my hair when the burned portion at left came out with the brush. I was mortified. Freaking out. Who burns their blasted hair when they blow-dry it? Really? I guess I wasn't paying enough attention, although it's never been something I really had to concentrate on. I mean I know that hair dryers burn but I haven't had an issues with this in the past. I was reminded of the time my sister burned the living room carpet with a blow-dryer when we were growing up. We quickly learned that dryers can do damage. I guess I just had to be reminded on Thursday.
