Things I don't understand:
Needing moral support to go and get a haircut.
I get being super fond of your long hair. I had wicked long hair that I wouldn't even trim in high school. It was long and it was double-tapped right in the skull dead but I wouldn't even think of trimming it.
But then I went and hacked it all off. And I went by myself.
You don't need moral support for a typical hair cut. It's a hair cut. It's hair. You're cutting your hair not donating an organ.
Just go and do it if that's what you want.
