What do we learn from the man’s reply?

W: Mike, do you still want to buy that large and comfortable apartment you looked last month?
M: I’m afraid I have to change my plan. I haven’t enough cash, and someone has reserved it.
W: Oh, it’s really a pity.

M: We’ll go for an outing tomorrow. Would you like to join us?
W: I’d like to, but I think it’s going to rain. The temperature is dropping.
M: You can’t be right. The weather forecast says fine weather for tomorrow.
W: I hope so. But I won’t take the risk. Thanks for asking.
M: Ok, then we’ll go without you.
