Hi. I'm glad I ran into you.
Why? What's up?
Would you like to go climbing this weekend?
I'm not sure. I promised to help my sister move on Saturday.
How about Sunday, then? We could start early in the morning.
I might be able to do that. Let me check and I'll call you up tonight.
Great! By the way, I won't be home before 10 o'clock.
Then, how can I reach you?
I've got an answering machine. You can simply call and leave a message. Your voice will be recorded.
I hate talking to a machine. It feels strange.
