Diary in English

My son is at home work by remote.
And he plays online game with friends at night.
So he doesn't move.

The other day he said "I have a back pain"

I knew. He is sitting all day long, in the same position, I knew it though I go to work everyday.

Well, as his mother, I say "Let's go and buy some ice cream, it's too hot" to take him out to make him move.
We did like kung-fu move (five steps) yesterday.
I found that I forget elementary tai-chi.
