Maybe, just maybe, if you happen to see someone doing something that may cause harm or damage, you ought to express those concerns. They don't have to listen, but perhaps the fact that you expressed a concern just might help them have a second thought about what they're doing. If you are wrong or they don't give it a second thought, no harm, no foul. Lord knows, none of us knows it all, and we sure don't have enough time to make all the mistakes ourselves, although I've been told that I do seem to be working on it.
