Where are you going that is so important

This poem relates to fathers and sons,but can be said about the time,space,feelings,thoughts,words,memories shared or not shared between any two human beings. I ask myself.where is it you are going exactly that is so much more important than this moment with this person right  now...

My friend says I was not a good son you understand I say yes I understand he says I did not go to see my parents very often you know and I say yes I know even when I was living in the same city he says maybe I would go there once a month or maybe even less I say oh yes he says the last time I went to see my father I say the last time I saw my father he says the last time I saw my father he was asking me about my life how I was making out and he went into the next room to get something to give me oh I say feeling again the cold of my father's hand the last time he says and my father turned in the doorway and saw me look at my wristwatch and he said you know I would like you to stay and talk with me oh yes I say but if you are busy he said I don't want you to feel that you have to just because I'm here I say nothing he says my father said maybe you have important work you are doing or maybe you should be seeing somebody I don't want to keep you I look out the window my friend is older than I am he says and I told my father it was so and I got up and left him then you know though there was nowhere I had to go and nothing I had to do
