do you think this is weird?

[stick it out]

i was at my grandmas house and i saw pictures of my dad with wat must of been his old girlfriend or something coz it wasnt my mom and he was young...and theres pictures of her and him kissing and i think it was a pic of her in a bikini...idk he is married does this seem a bit weird or am i just being paranoid? no rude comments thankss!!!
they werent around the house they were stashed in a draw in my dads old room and they were never married or anything i'm pretty sure..
