Joy

You know the feeling when a really bad day ends well? For example, you lose your purse or wallet, and then you get a loving phonecall from someone you totally adore?
You know the feeling when you are inexplicably down in the dumps, and then something happens to cause your heart to "soar like a hawk"? For example, you have spent the whole day grumbling and worrying about tasks not accomplished, and then a dear friend calls to tell you their operation was a success and they are back to normal?
I am sure the Greeks had a word for it, and at this moment, I really would like to know the Greek word for it. The English for it is JOY, and I am feeling joyous!
Wow, I just hope the sun shines again tomorrow.
