I was a little pass half complete with my exercise when Shos interrupted me and asked me to get something for her. She had to do something urgently.

While I was helping her, I lost count of how many squats I had done up till that part. I think I had done 64. But I couldn't remember.

I didn't want to do less than 100, so I started over. Why didn't I keep track? What made me lose count?
I was a little frustrated initially. I had almost finished my exercise, but now I had to start over. Why did I have to be interrupted?

I was tempted to be upset but decided to take responsibility for my actions.

One, I didn't have to stop. Two, I could have written down my progress. And at any rate, starting over wasn't the worst thing ever. I'd get to do more exercise. Couldn't that be a positive?
