One Time I Laughed Really, Really Hard

One time I laughed really, really hard I began to cry. I was moping my kitchen floor and I kept telling my sister and brother not to cross because it was wet and they might slip. Once I was done mopping I went to my room. My sister decided to be rebellious and go to the kitchen to get a cup of water then she slipped. She then slipped and fell. I went to the kitchen and saw my sister lying on the floor with the cup on top of her. I then began to laugh and I said, "You should have listened to me". It took me about a minute or two to help my sister up I was too busy laughing and the more I tried to control my laughter the more I laughed and then tears began rolling down my face. I then was a good sister and helped her up, I was glad my mom wasn't there or else I would have gotten into trouble if I laughed and didn't help my sister immediately.
