Has this ever happened to you?
Over the weekend we switched K's car seat to DH's car.  Well, this morning K was supposed to go to preschool (for a glorious 3 hours!).  At about 7 am DH left for work... WITHOUT switching the car seat back to my car.  
Cut to a frame of me doing a dramatic movie scream in slow motion, "Noooooooooooo!"
This means all of my lofty hopes for the morning - exercise, groceries, homework for my web writing class -- are dashed.  ARGH!  
After I told K, "I guess we're not taking you to your playschool after all," we headed back inside and came up to my room to flop on my bed and catch a little Sesame Street.  I thought a while about how we'll spend our new free time.  It's a sunny day, so we'll probably head outside and play in the sandbox.  
K interrupted my thoughts by snuggling up to me all of a sudden and announcing, "You are MY mommy!" 
I guess there are a few million things worse than being "stranded" with your cuddly son on a beautiful fall morning.
