Dear Ann Landers,
am a postal clerk, and every day, I see many cards, letters and packages sent to our mail recovery center (formerly known as the dead letter branch) because people do not put return addresses on the items they mail. I find it disturbing when mail that is undeliverable cannot be returned to the senders to let them know it didn't reach its destination. Think of the thank you notes, love letters, invitations and condolence cards that never got delivered because of illegible addresses. And imagine the hard feelings, disappointment, misunderstandings and broken relationships that resulted because senders didn't take the time to write their return addresses. When there is no acknowledgment of having received the gift, the sender assumes the recipient has poor manners. This problem could be remedied so easily. Return address labels are inexpensive, and it takes only a minute to affix them. Please, Ann, do your readers and the Postal Service a favor by printing this letter. It really IS important.

Dear N. Dakota,
I know a little something about mail and can sympathize with you. I hope your letter produces the desired results. Please, dear readers, pay attention to what this postal clerk is saying. It takes just a minute to print your return address in the upper left corner of the envelope or package or slap on the sticker. DO IT!
