Pizza at work as a celebration.
Happy hour with some fine people.
Laughing like crazy over funny jokes.
Riding my scooter around town on a beautiful day.
Going to lunch with a good group of friends.
Having friends who will tease you one minute and listen to your problems the next.
Spending time outside playing with the cats.
Having friends who I can ask favors of.
Being able to do favors for my friends.

As I said, lots of positive things have happened lately. :)
