Talking of 'apps', we went to make a Western Union money transfer a while back, and the chap in their little bureau said his computer was down. I thought he said, "You need a nap!" and I agreed, saying yes, I was feeling rather tired. He doubled up laughing and tried to explain what an 'app' is, but we decided to press on to another WU bureau and made the transfer successfully there.
Then we went home and I had an app!
