Signs your toddler may be ready to potty train even though you have done absolutely nothing to get her ready:
You are sorting though hand-me-down clothes and find a pair underwear in her size. She picks it out of the pile and delightedly runs to her room while exclaiming, "Mine! On? Mine! On?" You follow her to find that she has take off her pants and her diaper and is trying to put the underwear on.
I'm not ready! The house is too cold for a half-naked child (with a cold/cough!) to run around in and besides, Elaine screamed for most of four hours tonight!
