Waking up in your SO’s arms.
Seeing your parents’ eyes tear up with joy when they open your present to them.
Realizing that your favorite toy as a child is still the coolest toy ever.
Feeling like a part of the one and only SDMB.
Happiness is…
… different for everyone.
happiness is…
A release of endorphins in the brain causing feelings of stress relief and well-being.
… caused by a pint of really good beer with my SO and best buddies.
Happiness is the movement of water across a selectively permeable membrane.
No, wait, that’s osmosis.
Is happiness a sweater straight from the dryer?
Have you been studying too hard for exams again, KCSuze?
I would, if I hadn’t graduated. 
Is happiness the uppermost layer in our atmosphere?
No, that’s the ionosphere. Lemme show you what real happiness is…
grabs KCSuze and gives her a big ol’ wet kiss
Awww…<blush> So that’s what happiness is! Thanks, Q.E.D.! <gives him a big ol’ wet one back>
Jeez… get a room will ya!
Happiness is to crush your enemies, to see them driven
before you, and to hear the lamentations of their women. That and Code Red Mountain Dew.
Aw, but we haven’t even rented the goat yet! Spoilsport!
Happiness is:
The sound of silence when a baby stops crying.
Watching a father play with their child.
In-laws who are happy to babysit.
Having great sex whilst baby is at the in-laws.
Happiness is:
Having an automatic ice-cube maker and, thus, unlimited ice cubes…
A cold shower in the middle of the afternoon.
An air-conditioned room.
I think I’m a penguin.
Hearing my SO’s voice tell me that he loves me in voice mail.
My sometimes-distant kitty waking me up at 3 AM to love on me and give me kisses, even when I have to get out of bed in 4 hours.
Going down the interstate on a nice day with the windows open singing Fiddler on the Roof at the top of my lungs.

. . . A three-day weekend with two really good books waiting for me.
(continuing Eve’s theme)
…finding the new book you’ve been dying to read in the ‘new’ section at the library
…hearing parents kiss in the next room (yay, they still love each other, all is right…)
…laughing madly with your sister at an inside joke
…devastatingly good tiramisu/creme brulee/chocolate silk pie/flan/any sweet creamy dessert, really
… a warm gun (bang bang, shoot shoot).
… dropping by your DH’s office to drop him off a Hamburger Kingtm hamburger and knowing that you made his day.
Happiness is…
…temporary.
Happiness is . . .
a sunset flight on a CAVU day.
