was walking down the street when I was accosted by a particularly dirty and
shabby-looking homeless woman who asked me for a couple of dollars for dinner.
I took out my wallet, got out ten dollars and asked,'If I give you this money,
will you buy chocolate with it instead of dinner?'
'No, I had to stop eating chocolate years ago', the homeless woman told me.
'Will you use it to go shopping instead of buying food?' I asked.
No, I don't waste time shopping,' the homeless woman said. 'I need to spend all
my time trying to stay alive.'
'Will you spend this on a beauty salon instead of food?' I asked.
