My friend said "it's a beggers business!"

It's nothing like that. don't become depressed and nervous, few people react like this when they don't have any feelings of others they can not be called as friends I think. You are ought to meet some one like this out of ten. But there is a equal chance of getting rest nine as good people. Tell your friend that we are doing a sincere work and is no begging, instead you tell him this needs a heart and brain too not a business of fools. He will go quite, I am sure.
