One too many

I saw this man wandering around with his can of beer before he finally sat himself down amongst his friends.
I sometimes wonder what "street people" think.
Do they have regrets? What do they regret?
Can you really solve problems by drinking?
Do they yearn for their youth again? Another attempt?
Do they have children or siblings?
Are they totally lost or is it possible to communicate with them given a topic of interest?
