When my sister was 4/5yrs old she got assaulted by one of my guy friends, we were like 9/10yrs old. They took her behind our house & asked her to show them her vagina, they took pictures of her vagina & showed the rest of our friends & laughed about it whilst zooming it in & out, she told me they put a finger inside & I got angry. I told them to delete the pictures & they did.

It’s been years now my sister is 17 & I’m 23, I’m not sure if she remembers but it eats me up sometimes when I think about it, I’m worried that she sometimes remembers but doesn’t wanna talk about it, she’s never given me signs that she knows or anything even if we talk about sexual assault about other people or friends or things we see on tv.

Should I tell her or bring it up or should I just keep quiet & let it go?
