How do I find out more about her tattoo?

one of my female friends got a tattoo earlier this year or at least that was the first time i actually saw it , never did figure out exactly when or the story behind it. its on her ankle so i saw it during the summer when she was wearing shorts , but she's never really mentioned anything about it , it just sort of appeared , there was also nothing on her social media about it either and she wasn't following any tattoo pages on her insta. but she does for sure have a tattoo i saw it with my own eyes

i always wanted to ask about it but never have the nerve and wonder if maybe its not her only tattoo as often girls like to get them in places which are harder to see , so maybe she another one somewhere else if she is now into tattoo's
