Tattoos

I don't have any thing against tattoos but I think to a lot of people tattoos are socially unaccepted. But to others, they may like tattoos. For me I don't like tattoos on peoples faces cause its to distracting. Like I heard of a few people trieing to cover there whole body with tatoos. For the artists who do art like that I respect cause a lot of people can't duplicate a picture well and for them to be able to do it to every one who asks skin is a great thing. But I don't want one. It seems painful and time consuming and I wondered what's the difference between a tattoo, true art and graffiti.
