My daughter's school has a Maos Chitim campaign. This is a campaign that provides funds for matzah for those who otherwise would not be able to afford it.
My daughter is not allowed to go collecting door-to-door. However, she came up with an ingenious way of raising some money... she began selling a lot of the candy and nosh that she received for mishloach manos to schoolmates and contributing the money to the campaign.
It's great - it gets rid of all that candy, it raises money for the needy and it shows me that my daughter has an entrepreneurial spirit! I'm so proud of the little Wolfette!
