There are plans we didn't make that I think we did

There are plans we didn't make that I think we did make and as time goes on I am not at all sure of many things. 

I mentioned my regret at not keeping a diary. Jotting down little things that when they occur are meaningless and collect substance and importance as they grow old. What we had for dinner. What day we made love. How as it the love making. What the weather was like. Who I cheated on Melissa with. I did that. Why. I am not sure now. I think it was because we did not have the most free flowing and extemporaneous sex life. Maybe. Probably. maybe not. Of course not. But yes indeed. Who the fuck knows actually. 

As for the meories I do have why do I have them? Why these and not others. What about those events or places were so adhesive that they are still stuck to the inside of my skull. Would these same events have remained if we had just divorced? Would they. Hell if I know.
