A freshly mowed lawn (and the knowledge that you don't have to do it again for a week).
A newly-organized bookshelf.
A whole bunch of shows to watch on TiVO and all day to watch them.
A fresh cold can of the caffinated, carbonated beverage of your choice.
A nice cold glass of iced Mystic Chai.
A newly-made bed with fresh sheets that you get to sleep in first.
When the cat decides to cuddle with you, and purr, during your entire show.
When the cat decides not to purr in your ear at 1:30 a.m., but still cuddles with you.
When those bulbs you put in the ground some months ago and totally forgot about bloom into the most amazing profusion of flowers you've ever seen.
When you see a recipie on a cooking show that not only looks delicious, and not too expensive, but actually like something you could do without having to go out and buy new appliances.
A freshly vacuumed carpet.
A drainer full of clean dishes that you didn't have to clean.
Spontaneous cake. Or cookies. Either is good.
So, what random thing is happiness to you?
