[6] I had an upset stomach for lunch.

I had a family gathering yesterday because of my mother's birthday.

I had lunch for buffet.

-> I went to a buffet restaurant for lunch.

Honestly I'm going on a diet, but I couldn't eat a little.

There were various food just like Lobster, Lamb Coop, beef steak, sashimi, cakes and bakery.

I was so happy to eat everything.

I ate a lot without knowing it. Maybe I think I stood up on my seat to bring food about 5 or 6 times.

My mother was surprised at me. As soon as we arrived at home, she said why you had a lot of food.

I felt that I was quite sorry myself.

So I went out for running. I ran 10km. But it was not a good idea to run for losing weight.

I felt so bad. I had an upset stomach from lunch.

I made a decision not to eat a lot next time.
