Every second Saturday in May, the US Postal Service collects food for the Stamp Out Hunger Food Drive. It is the largest national food drive and it has helped deliver over one billion pounds of food over the last 22 years. I used this great opportunity to complete my twenty-first act of kindness. Li Na helped me pick out non-perishable food and together we left it by our mailbox for Lin our mail carrier. The food drive is held nationwide and anyone can participate by leaving food on or next to your mailbox for the mail carrier to collect!
