looking for and keeping traces

how reliable is memory?  it is so malleable.  so subject to change and to internal reverberations.  subject to certainty, to doubt, to nostalgia, to loss, to moments of eureka.  subject to internal resistances, to an extent of shared remembering, to a body or bodies of traces, often lost, often kept, often made.  so that.  sitting on this very same seat, by the very same window, at the very same time of the day on a summer, like now, like this, the same furnishings, the same tone, it makes you playfully wonder:  did it really happen?  did you really leave?  did you really just came back?
