What do you do after a game?

What do you do after winning/losing a game? Also what would you say to your opponent after playing this game. ( As black )

I thank anyone for playing me, and maybe it is habit when we're done to say "good game" because of the way I was raised (playing sports as a kid) .. win or lose.

..after a win or loss.. and after mating someone in two moves... I'd say: let me know if you'd like to play again.

note: I learned to play chess when I was a kid but I'd consiider myself a beginner.  I'm still learning, I didn't know what en passant was until about a month or two ago.

After winning, I immediately scan the game with an engine very quickly, to see if my ideas or combinations or whatever that took to win the game were right. After losing, I do the same thing but not immediately. Later (a few hours or days) I do in depth analysis.

After a win I always make sure to say "Good game". Sometimes my opponents even want to talk to me about the game and we both go over it. If no other conversation occurs, I take out my chess set in my room and look over the game again and write comments down. Then I put the game into the fritz 12 engine and see if my observations were correct, and more importantly, see possible variations and better moves I could have done. After a loss, I say Good game and take a rest. Play different games or watch TV. Then later in the day I'll do the same process as mentioned above.  :)
