一口飲む：ship

Yesterday I and my son was drinking water at the same table.
He was drinking it with his plastic cup as usual. I was drinking one with my glass.
Why different? I played a safe because he risked breaking a glass.

However, the water in the glass might have looked more delicious or something.
He asked me “Let me sip yours!”

Although I explained it was the same as his, but he didn’t listen to me.
Then he abruptly dropped the grass…
That was what I expected!

Anyway, I will play it a safe differently. I will avoid drinking in front of him.
