Be gentle. Everyone is fighting something.
The rude cashier. The impatient driver. The friend who didn't reply. It's easy to judge.
But everyone is fighting something you can't see. An illness, a debt, a heartbreak, a sleepless night with a baby, a quiet depression.
Gentleness doesn't excuse bad behaviour. It just leaves room for the possibility that there's more to the story.
Be gentle. You'd want the same on your hard days.
