Why we say it: Who knows!
Why this is a problem: People rarely change that much. Yes, teenage you is probably different than 30-something you, but 30-something you is likely not going to be that much different than 35-something you or 42-something you.
If you’re expecting your grown man to suddenly become a different grown man just because he put a ring on it, you’re setting yourself up for disappointment.
