Lee says It was tough to bury my best friend in the army today..
The friend responds I bet.  Sorry about that.  Where was the funeral?.
Lee responds It was in my friends hometown of Arlington.  Many soldiers were there to pay their respects..
The friend responds Did your friend died during warfare?.
Lee responds I was there when he died.  We were both out in the field.  I carried him back with me to our tank but he didn't make it.  I was so devasted..
