I'm usually pretty good with pain. I complain a lot about paper cuts and stuff like that, but with things like broken limbs or tattoos, I suck it up and take it like a man Smith person who can take pain.
The first time I got my ears pierced, I cried. Then again, I was four.
The second time I was eleven, and I squeezed my mother's hand.
The third time I was thirteen, and I held her hand.
When I got my eyebrow pierced, I was sixteen and held her hand; she was surprised I didn't cry or squeeze her hand.
I got my left ear pierced again, twice, when I was sixteen. I don't remember very well, but I think I held her hand.
I was eighteen when I got my first tattoo, and went alone.
Still eighteen when I got my second, and I held my brother's hand, only squeezing when I was intentionally trying to hurt him, just to see if I could. (He squeezed back, which hurt.)
The girl who did it asked if I brought my mother with me so she could sign the permission forms. Apparently she thought I was fifteen at the oldest.
