What part of "Just a trim, please" did my barber not understand? I was painfully clear: "I want to keep the length, but just a trim to clean up around the sides."
What I got is a modified crew cut. Not very helpful when I was hoping to grow my hair out a bit.
Argh.

Ugh. Sorry. That same thing happened to me almost 4 years ago when I asked for “just a trim” to my shoulder-length hair, and wound up with inch-long hair. I’m still recovering.
I am notorious for getting bad haircuts. I feel your pain.
