I know. That is why I believe it works. And we get bored and tired of the things we already have. It is like the kid who has a friend over to play. The kid hasn't picked up the G.I. Joe in 3 years. The friend comes over to play, sees the G.I. Joe, starts playing with it.. Guess what happens?
Suddenly the kid wants the G.I.Joe... They are then fighting over it....
Fast forward twenty years.. G.I Joe.... is now YOU...
You wife is the kid who hasn't played with it for 3 years...
The friend is YOUR new friend that you are spending time with....
Those old childish things we did back then are still somewhat within us... We may have matured some (at times I wonder if I have matured at all) but we still have those same tendencies deep inside....
