Every time I entered the room, Grandpa would quickly hide my daughter’s hands under the blanket… Until one day, without warning, I opened the door and froze when I saw what was happening.

My seven-year-old daughter Emily was extremely close to my ninety-year-old father.

Every afternoon, she would sit in his room for hours.

But whenever I entered, my father would quickly hide her hands beneath the  blanket.

One day, I asked Emily why.

She looked nervous.

“Grandpa told me not to tell you.”

That answer terrified me.

Then her teacher called and said Emily had been making strange hand signals at school.

When asked where she learned them, Emily simply said:

“Grandpa taught me.”

I decided to find out what was happening.

The next day, I pretended to leave the house, then quietly returned through the back  door.
