"Ugh, too much makeup!"
/When I was 16, I started experimenting with makeup. There was some family party I had to go to, and I spent a lot of time getting myself all dolled up for it. When I came downstairs to leave, my twin brother looked at me, made a disgusted face, and said, "Ugh, too much makeup!" Like I was personally offending him and hurting his eyes.
I still went to the party looking as I did, but I felt really self conscious the whole time.
And now, more than 20 years later, the entitlement and disgust he expressed in his reaction to my face still sticks with me.
