Letter to the person who shamed a mother using food stamps to buy groceries

"This is an apology to the lady behind me in line at Cub Foods in Edina on a recent Sunday night. This is also a reminder to me and to others who have ever slipped into believing that we are just a little better than others we encounter." Read: "Shamed in Edina for using food stamps," in the Star Tribune. [HT: @ClaraJeffery]
