Answer:
I was in class last week, and the teacher explained something and I just fell asleep. When I woke up, I woke up, I realized that everyone was look at me.
Yesterday I walked down the street, and I texted a friend when I walked right into a lamppost. I guess I did not pay attention.
My sister and her husband carried some dishes into the kitchen wen they both tripped over a rug. They dropped and broke all their new dishes!
Last week a friend of mine invited me over for dinner. In the afternoon, when she cooked, she picked up a heavy pot, and hurt her back.
