I'm close to my paternal grandpa. I looked up to him as a kid, he was a gov't official who I'm proud to say, was not tainted with corruption. He attributes his success to his faithful, loving and supportive wife. I still keep the pen he gave me when I was in grade school with the inscription ~ Legal Secretary, Office of the President of the Philippines.
My maternal grandma I called Nanay, was a petite, frail looking woman. Yet, she was the family's source of strength. She bore 12 kids, mom is the 11th child. When she became senile, mom took her in to live with us. I was a kid then and she acted like a kid so we got along well. I'd tell her secrets she wouldn't tell mom and we'd wink at each other often.
