Do things really happen in threes?

We can go forever it seems without anyone in the hospital and then suddenly everyone is in the hospital. We have had three different people go in the hospital this week. Patricia Interiano had gall bladder surgery that was not as routine as it should have been. She will be in the hospital a few more days. Jamie Smith spent a couple of days in but is now at home confined to bed rest for the rest oh her pregnancy. Monica Selby had out patient surgery but should be in church tomorrow. If everything does happen in threes, I guess the rest of us are safe until next time.
