I believe God wants you to know ...
... that the rule in carving holds good as to criticism;
never cut with a knife what you can cut with a spoon.
Charles Buxton said that and he was right. There are
very few good reasons to sharply criticize anyone,
least of all your idea that you know a "better way."
Continual critical comments with an edge can deeply
undercut confidence in a loved one -- and isn't that
the last thing you would want to do?
