I dated a woman once who, on coming home to my apartment, insisted that I was still in love with my ex (I'm not).
Why? Solely because she'd trawled through years of photos on my Facebook profile of the two of us together, looking very much in love (we were, at the time).
That feeling of capturing a moment can be very nice, but it can also be dangerous, and false.
(It worked out in the end...)
