I was hanging out at a girls house, and she picked my phone up while it was unlocked and started opening my snapchats and replying with pictures of herself and shit.

At the time I didn't really care, if anything it was making other girls speak to me more.

But now I'm thinking, should I not let her near my phone in future, to keep the whole mystery thing up? I found that she put her finger print in my phone and I'm assuming I should probably delete that.

Y'know if I'm replying to someone and she looks over, should you hide it or just carry-on?
