Can't Argue With That Logic

So, we arrived at the mall and Darcy had her shoes off in the car. When I told her to put them back on, she started throwing a fit.

Me: Darcy, you HAVE to wear your shoes at the mall.
Darcy: (random loud screaming about not having to wear her shoes)
Me: Darcy, you HAVE to wear your shoes. It is not MY rule, it is the MALL's rule.
Darcy: (hysterical screaming) It IS NOT the mall's rule!!! The mall doesn't have rules!!!! Look at the mall Mom - NO MOUTH!!!! THE MALL DOES NOT HAVE A MOUTH SO IT CAN'T MAKE RULES!!!!!!!
