Always end up saying "short but not too short"

"A little lower than my shoulders please"

"the same as last time"

"uhhh I want..."
*gestures vaguely*

"The usual please"

*points to hair* Everything below this, gone.

"Just trim the ends" works for me but I have long hair so...

"I don't want it short, I just want it less thick."

How short do you want them?
As short as necessary and as long as possible

Just ask your mum, no matter what age ask mum
