I gave my sister a piece of candy that was dirty after it fell on the ground.
You really did that? Aren't you worried about her getting sick from the candy?
No, it's just a little dirty. I'm sure she will be fine!
I don't think that what you're doing with your sister is very healthy and it can significantly hurt her health and make her very sick. Why not just prank her with more traditional pranks, like scaring her or hiding some of her stuff and that way she won't get hurt?
Alright, I won't do it in the future.
I'm glad that you won't do it again! I think you will be glad you decided not to do it anymore since I think you would feel bad if your sister got sick from the dirty candy.
