You are only 13, and even if you can get one at say 16 with parental permission, it's up to your mum. I know it can be hard to wait, but honestly, you should think months if not years on the tattoo you want, I've known what tattoo I wanted since I was your age, or just a little older, I still don't have that tattoo, and I'm glad because I've changed where I want it at, and even thought about perhaps not getting it, the fact is, we can think )that something is what we want and where we'll want it forever but when you get older and start looking for a job, you may realize it was best to wait if you did and maybe get it somewhere else.

Just drop it for now, she knows you want this tattoo, you've made it clear. If you can get one before you're 18 with parent permission, then bring it back up when you're old enough or almost old enough (like a couple months before your birthday) and then remind her about you asking when you were thirteen and how many years you've thought on it and still want it. That will show her you're serious about it, if you still want it years from now when you can legally get it. But chances are, most reputable places won't tattoo anyone until they are 18, and then you won't need permission from anyone except yourself.
