We go to bed with my wife, I stretch my hand under the pillow and touch her phone there. I ask :

What does your phone do under my pillow?

The wife says:

It will start to vibrate loudly, waking up the daughter.

Why not put it under your pillow? I ask you.

I am afraid it will explode. The wife answers.

O_O

Laughed a little. But the settlement remained.
