Bad Moods

Do I have a right to be in a bad mood?
If I could choose, would I choose to be in a bad mood or a good mood?

Is being in a bad mood a sort of entitlement?
Is it OK as long as you don't hurt anybody? But doesn't it almost automatically hurt people?
Is it just selfishness?
Or is it sickness?

Or do we owe it to our community to cultivate a good mood?

OK, so everybody gets in bad moods. What should you do about it?

Maybe the only wise course is to excuse yourself from the scene until the mood passes.
The problem is that you can't always get away. Sometimes you must work with others in spite of the bad mood. I can't work with you because I am in a bad mood so I will go by myself and relax and goof off!

Let everyone know you are in a bad mood and ask for tolerance?
Sounds manipulative. Sounds like shirking.
I can't work well with you because I am in a bad mood so you must accept my sub par performance.

How often are you in a bad mood?
How can you cultivate good moods?

This is a big field for study.
