17 Easy Ways to Respond to ‘What Are You Up To?’

A natural response to ‘What are you up to?’ is, ‘Not much, just finishing some work. How about you?’ Share one small detail and ask the question back if you want to keep talking. If you are busy, say when you will be free. If the message feels flirty, match that tone only if you want to encourage it.
