Why doesn't she want me to know that she has a small tattoo?

i've known her for some time , but she's never told me about her tattoo's. i only know about them cause i saw a picture of her on social media which showed them. the one is on her side rib area near her bra strap a common place for a girl to get one and the other is sort of on her hip near bikini line. both are relatively small and she had them for a couple years now and doesn't appear to have got any since

but never seen either when i've seen her inperson which usually has been at our local pub or downtown. she's never worn a top that shows her side rib tattoo i don't even recall her ever talking about tattoo's or has it ever been mentioned there that she has them , but must of been some point in her life when she was interested in them as she got 2 when she was younger

i'm not sure why it matter to her if i knew about them or saw them in person? we usually got along well and she seemed ok with me when we talked.

note i think she got the tattoo's around 2018 , there is an old picture of her on her old vsco page and it shows the side one but pretty sure she didn't have it before that year
