All excellent points. When I first started talking to my GF on OKC she kept going back to my profile to look at my pics. So I'd go to hers to look at pics too, sort of like an "I caught ya' creeping" gag (We still do this on Facebook. She'll casually mention some shit I posted years ago). Eventually I noticed that she was on there literally ALLLL THE TIME. I asked her if she was talking to someone else and she denied it. Eventually I realized that she was never closing the app manually between checking out my pics, so it was always running in the background on her phone.
As I said on this subject in a different thread (I think); Not everyone is some Gaffer nerd that manually closes each app as soon as their done using it to conserve memory. I mean, I do, but that kind of shit is important to me
Give the fellow the benefit of the doubt for now.
