<human>: Can you summarize the given text in a few sentences?

>I had a guy that used to come in all the time and buy two single black and milds. 
I finally asked him "Why do you always buy two? Why not buy a whole pack?"
He told me, "One of these is for me, the other is for my friend. He died, But I always smoked with him." This went on for a while, until one day he started buying only one.
I had to ask him, "Why are you only buying one now?"
He responded "I quit smoking, this one is just for my friend."

Obviously I don't know how much of this story is true, but I found it to be uplifting in a way.
<bot>: Guy bought two single black and milds regularly, only to smoke one for himself, and have one to immortalize his dead friend.
