If your brother buys you an ice cream ...
....
I'll be hungry ...
...
I will be happy if my friend ....
....
If my parents leave the house for a week ...
....
If it rains tomorrow ...
....
My brother will be mad at me ....
....
I will be sad if my friend ...
....
If I don't finish my homework ....
....
I will laugh if my friend ....
....
If I spend all my money ...
....
