This was me yesterday.
I grew my hair out so that I could eventually donate it to Locks of Love. I have had it long for quite a few years now and I have really enjoyed it. But it has started to annoy me and I have been ready to cut it for a couple weeks. Too bad I couldn't chop it off then. I had to wait for my hair appointment. As it got closer I got more nervous and attached, but in the end I didn't chicken out. I was able to donate about a foot (12 inches) of my hair.
