A story of a grandma

I have a story to tell.
Grandson: Grandma! It's raining! (shouting)
There is no response.
Grandson: Grandma! It's raining! (shouting by raising his voice)
Still, there is no response.
Grandson: Grandma!! It's raining!! (shouting, until the whole neighbourhood can hear, and the grandson suffers from sore throat after that.)
The grandmother walks slowly out of her house, looking at the sky and grumbles, and to the extent of scolding.
Grandma: How come you (as in the grandson) did not even make a noise that it's raining? All of my nearly dried bedsheets went wet!
Sadly, the grandson goes into the house silently.
