What about? -vs- How about? ...and Will -vs- Shall
This issue has always confused me:
Hi! How are you?
-I'm great, thank you. What about you?
-I'm great, thank you. How about you?
-I'm great, thank you. And you?
What's the more natural answer? Are "how about" and "what about" interchangeable?
I can't understand the difference very well, I always seem to choose the incorrect one.
How was your day?
-It wasn't bad! what about yours?
-It wasn't bad! how about yours?
-It wasn't bad! and yours?
(same problem...)
-What about going out tonight?
-How about going out tonight?
(same problem...)
Any help appreciated.
