A saxaphonist nearby busks for his daily living, hoping for some pitance from passersby. They throw him a coin or two, listen for a short while, then continue on their way. He treasures every coin, cause thats whats going to earn him a little dinner for himself. He hasn't eaten the whole day, and continues to play on through the night as long as he can.
A drunkard hobbles slowly along the footpath, shouting randomly at anyone that gets his attention. He's unshaved and hasn't bathed for weeks. He holds his bottle like a vice, and drinks from it from time to time. He goes towards the saxaphonist and utters some more random words. He's a public nuisance and pisses on the streets. No, the rest of the folks aren't amused with what he's doing and they don't give a sh*t.
A group of homeless folk sit down on a bench, talk among themselves and share a cigarette. Though the city council does give them some cash to tide them over, they instead spend it on booze and drugs. Unless they get a real job, they'll most likely in that same situation for a very very long time. They've only got their fellow homeless friends to keep them company. Things get worse with old folk. They're usually on their own, and just make do with whatever there is, usually a park bench. I've seen a fair share of them all these years. Only God knows if they'll ever be remembered when they pass on.
