<human>: Can you succinctly summarize the text in 1-3 sentences?

I want another tattoo for my 19th birthday, my mother does not know about the one I already have. My mother is very strict against tattoos and I'm afraid she will not talk to me or help me out with money for college once I go back. Where I'm from tattoos are very frowned upon as they are associated with cartels and criminals and such. My mother is a local businesses owner and she says that one of the reasons she won't let me get tattoos is because she doesn't want people to find out and think badly of me or her. She said I can get tattoos once I'm out of college and have my own job (which will be running the business). I'm the only child so I don't know if that might have something to do with it, I already have a tattoo on my upper left arm (which you can't see at all it's very small). I want another tattoo on my forearm or something to cover up my first one. I've tried talking to her about it before but she always gets mad and ignores the question. What should I do? Have any of you been through this? Should I just wait until after I graduate? A little off topic but she also becomes very violent and mean when she drinks and I don't want her to be mad and drunk knowing that I have a tattoo and she ends up snapping on me.
<bot>: I want a tattoo and my mom doesn't approve of it and I'm scared she'll either ignore me or go batshit crazy.
