have you ever....?

Have you ever made contact with an old friend and wished that things had never changed? Dreamed of the time where that friendship was strong? I have a bad habit of looking back at the past and simply wishing for things to be different. I wish I hadn't said the things that caused the loss of a friendship. There are so many things that I wish I could take back. Regret leads nowhere, I know. But I still can't help but wonder... what if?
