I once took my grandma to the movies and ate an entire party bucket of chocolates during the movie that I was suppose to share with her. My grandma was annoyed. Yet I never regretted upsetting her that day
Why did you eat so many chocolates? What did your grandma say?
In the middle of the movie, I gulped down a whole lot of it in a few seconds in a disgusting manner. Grandma found it very nasty and she asked me to stop eating in a louder volume. She asked me to share any leftovers with her when we got back home. But I couldn't be bothered to take along the leftovers, so I ate the whole bucket.
I can hardly resist chocolate either, but you shouldn't have upset your grandma like that. In the future, make sure you share with her.
It's just something stupid I did in the past.
Everyone does silly things when they are children. Your grandma probably finds it amusing now to think back at that time. I would call it a funny story and nothing else.
