My new haircut

I finally cut my hair after months of talking about doing it. I hadn't planned on going super short, but my stylist insisted that this cut would look great on me so I went for it.  I really like it. People I don't even know are commenting on this cut constantly. It seems like everyone has an opinion.  This happens every time I cut my long hair short. The weird thing is that people keep describing it as short and "sassy". I think sassy is the last word I would use to describe myself.  One engineer at work (with admittedly little social skills) told me that this cut makes me look 12 years old.  Another engineer reacted by yelling "what did you do?!?!" in the cafe at lunch.  A girl in the restroom looked at me and said, "wow, it must have been so hard for you to do that to your hair".  I don't know how to react to these comments.  Good think I like the cut.  Otherwise I would have freaked out by now.
