I just had a sudden (and fleeting) urge to see an ex of mine. In times past I may have just gone to his house when that urge hit, which is one of the many many reasons I moved. In any case, what went through my mind in response to this longing was, "Well, I can't jump in my car and go see him." Took me a sec to realize just how true that was.

The secret to happiness is not having what you want, it's not wanting what you don't have. :)
