We all have uncomfortable moments in life.
It may involve realizing we had a stain on our shirt all day, or accidentally pushing on a ‘pull’ door but those moments hardly ever cross the line from embarrassing to painful.

A comment made ‘in good fun’ could in fact be disturbing to the one addressed. Such actions are called ‘microaggressions.’
