I'm still reeling at the idea of you only age 25 yet you published a book of short stories (I have it in my Kindle still even though I no longer remember the author name!).
Your friend has strong opinions and weak character....?
Funny, where I live, rainbow hair seems quite common among the elderly.
Maybe because the white base is a good foundation.
What I want is the freedom to NOT spend time and money (and a carbon footprint) on hair dye, salons, makeup, botox, the latest fashion, nail polish (and remover), cologne -
I am turning into a troll. The old hag of the forest.
Except, I do tweeze out facial hairs, and I've had moles surgically excised.
Now to exorcise my inner hag.... or not. I am inclined to let my unkempt old woman with gray hair and wrinkles proclaim I EARNED THIS - I is OLD, and I am grateful to have lived long enough to let it show.
Well, purple hair, if you wish, is your prerogative.
"Too old" - who is this woman, speaking this nonsense to you?

You be you. She can be she. I'd rather be you.
