I'm going to give a potato to a beggar.
Why would you give a beggar a potato?
I'm hoping that if I feed him he'll come back to my home.
It's nice that you want to get food to a homeless person, just make sure that it's cooked. Giving a raw potato to a beggar would be mean if he was hungry and couldn't eat it because it wasn't cooked.
Betty crocker and pam could solve a lot.
You don't sound very sincere. Most homeless people didn't choose this lifestyle. Playing a practical joke regarding food on a homeless person is cruel; put yourself in their shoes.
