Maggie: I don't feel well today.
Vince: If you feel sick, go to the doctor!
Maggie: I don't want to go to the doctor. If I go to the doctor, I will have to pay a lot of money!
Vince: If you don't go to the doctor, you will be more sick!
Maggie: I know. I don't like feeling this way. If I don't go to the doctor, I will rest at home.
Vince: If I come pick you up, will you let me drive you to the doctor?
Maggie: That's very nice of you, thank you.
