wigs and perception

i went to see a friend who is in the midst of a series of chemo treatments.
she had a cute new wig.
it was grey like her hair, or almost like her hair.
just for fun i tried it on, and to our surprise it matched my hair perfectly.
she said she'd give it to me when she's done with it.

i came home and told john about it, told him it was the same exact color grey as my hair.
he said with surprise "your hair isn't grey"
curious, i said "what color do you think my hair is?"
he said "it's blonde, of course!"

hahahahahahaha 
i wonder if when he looks at me i'm also 25 and don't have wrinkles!
