Is there any difference between Despite and In spite of?[/i][/quote]<<Originally Posted by maestra
They both mean the same thing. It's fair to say that they can be used interchangeably.
You are correct about the difference between "how about" and "what about".
"how about" This is used to make a suggestion.
"what about" This is used as a reminder about something. It is like saying "Let's not forget about......".
Additionally, I would say it has more of a suggestive quality to it because it is an interrogative.
If we say, "Let's not forget.....", it sounds more like a command. (Actually, I'd say it is.) It's a negated imperative form. (first person plural) It is a stronger sounding statement.
I hope that helps.
