My husband travels on occassion for work.  When he does, I gather the boys in my bed and I try not to worry.  I worry about the safety of my husband, the house, life, etc.  I have sleepless nights until he comes home.  Trust me, this is not a rant.  This is just how much life is when he's not around.  I listen for every sound and movement, I think about all the things on the to-do list that need to be done before he gets home, I ponder my ability to accomplish things without falling apart.  LOL  Crazy, I know because I'm sure he doesn't do this when I travel...lol.  Actually, when I travel, the same thing happens except I can't gather my boys in my bed.  I still worry, I still think, I still have sleepless nights.  Insane, I tell you!
