Tattoo Advice

Tegan
Hey ladies! I recently turned 18 and I'm thinking of getting a tattoo. Problem is, my parents don't want me to get any while I'm still under their roof. I'd like to try and convince them with the fact that I'd pay for my ink and that I'd get it in a place that's easily hidden (They're worried about my chances of getting a job with a visible tattoo. They recognize that the stigma isn't exactly right but that doesn't change the fact that it's still a problem in the workplace.)
Long story short, I need advice. Where are some spots that are easily concealable, will fit a relatively small tattoo, and what's the pain level of that spot?
