Go / Went / Gone

I said goodbye to someone leaving last night.
He had two big pieces of luggage, a backpack and a laptop...
But, I believe his heart was not that loaded with the heavy burden of stability like mine...
I said "goodbye", he said "we'll see each other again"...
I left for home, he stayed sitting there at the bench.
Actually he was the one leaving, not me...

Now I'm waiting for another friend of mine to leave in a couple of months.
I don't think I will feel any different than I had yesterday.
He's gonna go away; I'm gonna stay.
And I'm gonna feel the bitter pain of standing where I am, where I was.

All I can think about right now is to leave, to go away.
Even without any luggage, without any money, without expectations...
And I keep repeating the verb conjugation: Go, Went, Gone...
