It seems awkward, or unexpected, or untoward to say how you feel, so you don’t. It seems like you have a friendship, a rapport, maybe a better chance to say it later, to lose. But things have a way; they conspire to lose you the things you are trying not to lose.
What is worth giving up in order to be calm and happy?
Have you ever made a commitment you thought you wanted, then been relieved when it became impossible to fulfill?
Have you ever woken up with a dream you wanted to remember, but lost it an hour later?
Have you ever watched someone or something get carried away from you?
Of course nothing lasts forever. But nothing lasts for very long. Have you ever gone somewhere, done something, known someone, being especially aware how soon it would blow away. Was it better that way?
This is one in a pair of installments I did, diptych style, based on a few simple birds flying. The other one is found just behind: http://secretvespers.com/2009/01/06/birds-back-v1/ Have you ever been left like this, with a need that seems to last forever?
Have you ever hoped someone would miss you?
