Here’s the rule about telling someone about something wrong with their appearance:
If a person can fix it in 5 minutes or less, tell them
If they can’t…
That’s actually a really good way of putting it.
This is a good rule. Spinach in their teeth? A flyaway hair? Stain on their shirt? Yeah, tell ‘em.
You think they’re overweight? You don’t like their hair color? You think they’re wearing too much makeup? Shut up.
