She might be hiding her tattoo from me and not sure why?

well i'm not sure she actually has a tattoo there or not , but i've never seen it so if she does then she's been hiding it.

i'm suspicious cause a number of her close girlfriends have one in that location ( side ribs ) , the same location i speculated she might have one. a popular location that a lot of younger women seem to get tattoo's done these days

one time at the gym , i though that i might of seen something there but it happened so quick and she acted really weird when she walked by , she's also not a regular member and the few times i saw her since she was wearing t shirts that covered it. i though that i saw a black line or something but was so brief. many popular female tattoos like roses or flowers have small black lines in the design often at bottom so might of just seen small part of it

but can't find any proof she has one like no recent pictures and never like asked her about it , she does have a small tattoo on her ankle , got it a couple years ago and i saw it that summer cause she was in shorts. but she wouldn't like talk to me about it even though i obviously noticed it on her

i just find the whole thing perplexes me? as to if she has one there or not and if she does , why hide it from me all this time as i know her fairly well

it was really hot here the other day and she had been out boating and appeared at restaurant in a more revealing top which showed her side rib areas and to my disappointment was no tattoo visible. possible she still has one somewhere else that is harder to see but not in spot i though
