to ink or not to ink?

A group of boys in the neighborhood asked me yesterday if I'd want a henna tattoo. Well, I didn't think twice about it. It's just temporary anyway and it's free. One guy made a drawing at my lower back and another did the inking. The result was nice. It was clean, no blots, and I didn't have any allergic reaction to the ink. They told me that they also do permanent tattoo for a very cheap price. They said that I all I have to do is find a design and buy a needle. However, that thing needs to be thought over several times.

I've thought of having a tattoo for three years now. I've searched the Internet for a good design. I opted for a Kanji character for fire. But when I think of it over and over, it seemed that I had more reasons not to get one. It's easy to get yourself inked, but it's difficult to have that erased. I saw my supervisor getting a tattoo and I could only imagine the pain just to get that. Besides, if my father and my mother will know about it, they would probably kill me. Getting a henna is easy anyway.
