Question

Is this dialog ok?
A.  What are you two doing?
B.  We're just doing some friendly chitchat. or  We're just chitchating.

Answer

A. What are you two doing? OK
B. We're just HAVING some friendly chitchat. or We're just chatting.

Answer

It's fine.

Answer

A: is correct.
B: Either; "we're just having some friendly chitchat." or "We're just chitchatting."

* The sentence "We're just doing some friendly chitchat." sounds awkward since we do not use the verb 'to do' when referring to conversation, rather we use 'to have'
