Liz: Hi, Tom. It's my sixteenth birthday soon. I want to invite you to my birthday party.

Tom: Cool! I remember about your birthday on the seventeenth of April. Is the party on the same day?

Liz: No, it's Friday. I have my guitar lessons on Fridays. The party is the next day, on Saturday the eighteenth.

Tom: Oh, no! I have to go to my grandparents on that day.

Liz: That's a pity … When do you want to come back? Maybe, I can have a party on the nineteenth, in the evening ...

Tom: I'm not sure. My parents want to come back on the twentieth early in the morning. But I can ask them to return on Sunday afternoon.

Liz: That would be great!
