She asked, "Mom, Uncle Kenneth is you brother right?"
To which I replied, not wanting to confuse her with the "in-law" tag, "Yyyyeeaah... sorta. Why?"
"Then how come you and Papa are married? Shouldn't Papa be your brother???" came the shocked reply!
I didn't have the heart to confuse her any more. After all, my Dad married my Mom, my grandpa married my grandma and my uncle married my auntie!
