A local charity had never received a donation from the town's most successful lawyer. The director called to get a contribution.
" Our records show you make $500,000 a year, yet you haven't given a penny to charity," the director began. "Wouldn't you like to help the community?"
The lawyer replied, "Did your research show that my mother is ill, with medical bills several times her annual income?"
"Um, no,"said the director.
"Or that my brother is blind and unemployed?" The stricken director began to stammer and an apology.
" Or that my sister's husband died in accident," said the lawyer, his voice rising in indignation "leaving her penniless with three kids?"
The humiliated director said simply, "I had no idea."
"So, if I don't give any money to them, why would I give money to them, why would I give money to you?'
