Aiden: Listen, what time do you want me to come tomorrow?
Aiden: 20:00? Earlier? Do you need any help?
Aileen: No, I'm ok. Be there at 20:00 or around 20:00 and it'll be fine.
Aiden: Okey.
Aiden: What shall I buy?
Aileen: Something to drink, like wine or beer or whatever you like.
Aiden: That's all?
Aileen: Yes :)
Aiden: OK :)
Aiden will buy something to drink and come to Aileen's around 20:00.
