"We make them, we break them, because some promises are very hard to keep. Here are the top six most common broken promises ...
1. I'll come back tomorrow. (plumbers, builders, electricians)
2. I won't tell anyone. (when somebody wants to tell you a secret)
3. This won'r hurt. (doctors, dentists, nurses)
4. I'll write. (new friends on holiday)
5. I'll pay you back tomorrow. (when somebody borrows you money)
6. I'll always love you."
