forgotten about you lately,
forgotten about the time-lapse.
There have been no tea light
memories of you, no language hidden
in what I've said. I had neglected
your arrival and departure,
departures and arrivals,
This is a tricky piece. I'm not sure how to interprete it but the sadness and "the not caring much" undertones within the lines are felt. What I think, it's that the author forgot mainly about the departures or at least tried to. The sense of what I get when I read the poem, it's that of a person having a conversation either with someone or just with herself.
This piece reminded me of someone who no longer cares. It's like that someone whom this piece is directed at, left often which made the author feel perhaps alone? and at the same time, the distance made the author feel unattached from that someone whom this piece is directed at.
So, slowly, the author is forgetting about that someone. It's sad when relationships don't work due to not investing enough time to each other. :(
That's pretty much what I understand from reading this piece.
