When I attended the meeting about the company safety, I was taught that 13 pieces of cube sugar are included in sweet drink in plastic bottles.

A carbonated beverage seems to be included more.

-----

For a painful game, I heard that foolish game "how many cups are you drinking soy sauce?”(Don't do it. It is really danger)

The parents, who don't stop their children to eat more than 13 pieces of cube sugar, seem to be having an abuse perfectly.

So I told my daughter about the 13 pieces of cube sugar.

But I am afraid that it is not enough.

Next week end, we are going to go a family restaurant and order free drink menu,

I will hold an event that,

Lining up both a cup of tea with 13 pieces of cube sugar and a glass of carbonated drink, and ask them to drink two at the same time.
