A:How’s your mother these days? (How is her general health?)
B:Oh, she’s fine, thanks.
[talking about an old house]
A:How are the walls in the kitchen? (What is the condition/state of the walls?)
B:Well, they need redecorating really.
A:How’s your new car?
B:Wonderful. It’s so much easier to drive than the old one.
