1. A Lot of people, A LOT, of people have tattoos on their wrists. It's not going to hurt you to get one there, but just be prepared to have it permanent.
And I know that sounds really trivial, but be ready to accept it. For example, at your job, you might need to cover it because it's unprofessional.
Just seriously, think about the consequences and stuff, and extra care you'll have to take, and remember that it's permanent lol
And if you still want it, go for it
2. I have a silver A and a gold A necklace, made from chains that I went out and bought, and just attached the A's from the AT08 pouch, and the AT08 key ring to.
I <3 them. Although...everyone asks me what it says in Japanese

Apparently it looks very much like a Japanese character to Americans.
