This sums up marriage so well.
Half the time I don't know where my husband is going to work (he's a sound engineer and works a different 'gig' everyday). I do know he loves his work and enjoys making great events happen each and every day. I know at the end of his work day, could be 4 hours or 26 hours, he comes home to tell me how it went.
Marriage is a partnership. Ying to Yang.
