Technology dependence can work against us

There's a cute story by Arnold Lobel called, "The Letter." Toad is waiting by the mailbox, sure he's going to get a letter that just never comes. Frog decides to send Toad a letter to make him happy. Frog gives his letter to Snail, who agrees to deliver it. Frog rushes back to Toad's house and together they sit waiting for the letter to arrive. They wait four days. Snail mail is a little slow. In "Snail Mail Revisited," the author shows how too much dependence on technology can be a liability.
