A Rain Check
It’ll be terrible if it rains tomorrow (1). If it rains (2), I will have to postpone the party. I don’t know if it’s going to rain (3). If I cancel the party (4), I’ll have to call people. What should I do if they have already left (5). If they come to the house and no one is here (6), they’ll be upset. I’m not sure if I should cancel the party anyway (7). If I cancel the party and it doesn’t rain (8), I’ll be upset. Come to think of it, I will have the party even if it rains (9). I don’t really care if it rains (10).
