It is true "if it sounds like a rule, it's probably wrong." The exceptions
are Coach Smith's rules :1. Feed the baby. 2. The mother is right. 3.
It's her baby [usually!] 4. Nobody knows it all. [also have heard "nobody
knows everything"] and 5. There's another way. I've have also admired
Dr.Woolridge's "the rule is - there are no rules!" Sincerely, Pat in SNJ
