- Telephone conversation...Ana: Hello Ben!
Ana: I phone to say you that tomorrow there is a party. It will be at Mary's house.
Ben: Oh! I'm sorry but I'm sick, I have a fever...I am not sure if I will be better tomorrow. But I think I may go.
Ana: Ok!, I like that you think positive. Bye!
Ben: Bye! thank you for calling.
- In a forced landing:
"The airplane may not land on the sea because there are some boats!"
- We are out of school and we go to my car, but my keys aren't in my bag...
Susanna: Perhaps your keys are in your house...
I: My keys mightn't be in my house because I have driven my car until here, so they must be here!
