We can sometimes sense and feel someone even more when they are not with us, when we are being still/quiet - having that sense of being, opposite to calm… as you expressed.
Something about this makes the poem more beautiful…it almost bespeaks your username to me…but it might just be me and not what you meant it to be…impossible dreams, love lost, futility…
