Laughing really hard. Giggling as an adult like you did as a teenager.
Having so many conversations going on, all at once with a friend, that you keep losing your conversation thread.
Seeing a friend after 20 some years and being able to instantly start having fun with them again.
Finding out at age 64 that you have a number of friends who still smoke pot and would welcome a chance to smoke pot with you.
The feeling in your heart when you know you did something to help someone else.
Recognizing your own personal strengths and thinking they are good ones.
With age comes the ability to bounce back a lot faster.
The feeling in your heart when someone demonstrates with an act or word that they really love you.
The way you feel after exercising.
Oh beloved readers – Please, please share a few of your own.
