Undeserving
You may be the undeserving recipient of someone else’s disappointment. And it might be totally unrelated to you … except that you’re the recipient.
Likewise, you may be the undeserving recipient of someone else’s joy.
This is the way things work; lots of feelings are misplaced in the world.
When you can, be someone who spreads joy more than disappointment. It’s a virtuous cycle worthy of your contribution.
