Pretty funny this cause I've used some of them:
1. I won't laugh, I promise.
2. Your table will be ready in a few minutes.
3. I'm just kidding.
4. I never got your text.
5. I have read and agreed to the terms and conditions.
6. You will need to know this later in life.
7. I'm fine.
8. Okay, just one more episode.
9. I'm on my way.
10. Sorry, my parents said no.
5, 7, 8 and 9 I have used before. How about you?
