person A: A homeless woman asked me for money and I said no.
person B: I don't blame you.  I don't like giving out money like that - you just never know what they may do with it.
person A: I feel so ashamed not to give her anything.
person B: Well_comma_ like I said_comma_ you couldn't be sure that she would use it in a good way.  She could have bought alcohol_comma_ etc.. with it.  What I usually do is if they are asking for money for food_comma_ I will go and buy them a meal or go get them some groceries that aren't perishable.
