hair angst

I'm visiting the parents house for the weekend. My Dad is visiting the Grandmother for her 90th birthday in Wisconsin so it's just Mom and I kickin' it girl style this weekend. We have a billion errands planned, and some fun stuff. Mom thinks we should go and get me a fancy salon hair cut....only I'm having hair angst! I chopped it up to my chin 2 years ago and it's only now starting to get long-ish again. I know I need a trim as it's very ratty..but I can't decide if I want a big chop or to keep growing it out. I don't DO anything with my hair, I don't blow dry it, flat iron it or curl it anymore. I just braid it or put it in a bun...so why do I spend 99% of my life with long hair for the 1% that's costume hair? Especially as I do like two events a year...even so I'm having a really hard time with the thought of cutting it off :-/

What do you all do? Anyone chopped it and regretted it? Wish you had chopped it? Most liberating decision ever?
