I want to get a small tattoo for my dad. I have one for my mom, a carnation with her name in the pedals. She loved carnations and it's the mothers day flower, so that was an obvious tattoo. But my dad doesn't really love anything like that. What could I possibly get for him? He's mexican, he was a hard worker, he came here young, he likes soccer (could have gone pro if he hadn't come to the states. He likes knives too. He always supported me and was the only person in my life to go to all my baseball games and boxing matches. I really want to get something to let him know how much I appreciate him, even if we've had our differences. Thanks for any help in advance.
