My thinking about Tatoo

Tattoo is a message or a way to express one's identity, character, thoughts (pl), etc. In our society, any expressions about one's thoughts (pl) is enabled, and the tattoos (pl) are is the same case. Through the tattoos (pl), we can make my another image or express my thinking  thoughts without talking.

However, tattoos have has the negative points, too. First of all, it is not easy to remove  delete. If the children get have the tattoos (pl)  without deep considerations, it is recorded for all their lives (pl). So, we should be cautious getting the tattoos (pl) in on our skin.
