Keep an eternal perspective...a lesson learned while playing a game...

I really enjoy playing games, and one of my favorites is, "Ticket to Ride." 
We decided to play a round, usually it is really fun and we are all laughing and having a great time. This particular instance however, it went from fun to serious in a matter of minutes.
Let me explain...
I will change the names to protect the innocent, after all, this is my lesson.
If you don't know how to play this game, the object of the game is to place pieces on the board  trying to make trains to complete a route that you have chosen. I had my specific route, I knew my destination and I knew what I needed to do to get there. I formed a plan and proceeded to carryout that plan. Little did I know that my plan was in direct conflict with someone else's plan. Every time I placed my trains to reach my destination, my fellow players were getting more and more frustrated. (I will call him-Chris) was getting blocked at every turn, and getting um...:) So, in the middle of the game, things were getting a little heated, no one was laughing anymore, everyone was focused on the game, there was no visiting-we were serious. I ended the game with my last piece. The End.  We were counting up the points and Chris realized he didn't do as bad as he thought he had done and was actually in 2nd place. We put the game away and all went our separate ways. I went into my room thinking about what had just happened...where did things go wrong? What could I have done differently? What could I do now to heal the hurt feelings?  Just then, Chris walks in and kisses me and tells me he loves me and that he is sorry he was being such a stinker during the game.

It was just a game, why did we get so caught up in the game and forget about each other?  What other things in life take the Eternal perspective out of our view? What other things distract us and cause us to lose our focus even for a moment? Why do we allow ourselves to get distracted over silly things?

I want to do better about staying focused and focusing on the things that matter.
