Old pictures
I was at my grandparents' house the other day, and they gave me some old pictures that they had found lying around. Some of them were of me and my ex. It really struck me - first of all that I still have a strong emotional response to seeing her face, and second of all that I had almost forgotten what she looks like. Of course there was some reminiscing afterwards, and thinking about how stupid I was back then, and how bad we actually were for each other. But at the time it was like I had found my soulmate. Weird how perceptions change.
