回复：I give them a warning,

"I am about to lose my patience", and mess up my hair to let the hair stand on their end like a mad mad lion or tiger... That amuses them and stops whatever mischief they are in immediately. The problem is they reply."more more, that is funny, mommy , show us more of your mad face."

Thanks for your advice. From now on, I will run into the corn field and yell as loudly as possible, except that in winter, there is no corn field to cover me. Hah.
