Here is a dialogue:
Eva: Can you come this evening?
Susannah: Yes, for how long?
Eva: 7 - 11pm?
Susannah: OK :-) Will be there.
Eva: Thank you. The food is in the fridge. Liz should be quite tired after dancing, so she shouldn't give you any headaches :-)
Susannah: No problem and don't worry. Have fun with James!

Write a short summary!
Susannah will come this evening and stay with Liz from 7 to 11pm, while Eva is with James.
