Mother in Law secret identity revealed

For many years i always knew that my Mother in Law had a secret, and i could never put my finger on it, A wonderful lady always full of beans, a warm and fuzzy lady who always kept going no matter how hard life became,

Always there for my wife and i, with her advice and all knowing awarness of the world around her, a very wise lady who i thank for the wife she gave me,

I often think what kind of world would it be if it was not for super hero's like her, saving the day and pointing my wife in my, i mean the right direction, so i would like to share with all of you her secret identity, and for the recognition she so deserves, i decided a picture of her would explain it all, and open the question to all of you, does your mother in Law have a secret identity also?
