Yes, I actually also wanted to write on the beggars, but decided not to, because the post would become to big, but the sort version is, that beggars make more than a gardener, thus it is easy to just beg - and you are correct most of them are on drugs or liquor!!
It is just sad.
Yeah its very sad. I can see there are so many that asked for money. And some are so Jung maybe 14 years old.
