Sandman’s Dilemma

My kids tell me they cannot go to sleep.  When I ask them why, they tell me they do not know.  I look around, trying to figure out why, and I think I have figured out the reason.  I think that the Sandman is afraid of something in my house so he avoids us as much as possible.  The question is what is driving him away.  I originally wonder if the kids themselves have made him scared, but I can’t figure out how any of my angels could put that much fear in a mythical level being.  I move onto wondering about my snoring, but since I am not asleep as well that cannot be the case as well.  That leaves me one explanation.  What would cause fear to set a single step into my daughters’ rooms?  What could cause so much pain and suffering that the Sandman would rather take a hit to his mythical stature than do his duty in my house?  The answer is simple my friends, Legos.
