Last night I woke up to this big thump on the floor.  I could vaguely remember rolling over and hitting something with my hand.  So I looked down and there was poor Maggie, looking dazed after I basically threw her off the bed.  Poor girl.  And now I know that once we have kids, we will not be a family that co-sleeps.  As my family and all of my roommates know, I cannot be responsible for what I do when I'm sleeping.
