I remember my friend, and then again I go back in time

Then again, I become that boy,
The one who met his friend on a Friday, in the living room, after his swimming lesson

Then again, that boy,
Who ran with his friend on the streets in spring, in the parks in summer, played the fields in autumn

Then again that young man,
Who dug a hole with his dad on a Saturday, stood that morning with his family, as his friend went into the ground

Then again, that young man
Who with head in his girlfriends lap at night, drunk in the dark, cried for the loss of his friend
