What was it that you could have said? There are relationships that have suffered because you did not say the right thing at the right time and now the guilt is bearing down on you. Also consider that maybe it was best not to have been said. But if it still need to be voiced, there is still time. But first you must forgive yourself for letting the opportunity pass you by. If that person is no longer among the living, they will still get the message. If you are not longer speaking and they won’t return your calls, write it in a letter and set it on fire. Otherwise, it is time to pick up the phone and clear up the past.
