About a year ago, when Mr W was about to turn 4, he realized that my stepmom was not my real mom. How, I don't know.

"Daddy, if N*** is not your mommy, then where is your real mommy?"

"Well, Mr W, my mom passed away a few years ago."

"You mean your mommy is dead?"

"Yes."

Mr W starts to cry. "Oh, Daddy, I am so sorry!" And gave me a big hug.
