Arrangement - Invitation

Invitation

Asking about people's arrangements:
Are you doing anything next friday?
Are you free on wednesday?
What are you doing on tuesday?

Inviting someone to do something:
Would you like to come?
Why don't we meet for a drink?

Saying yes or no:
Yes, I'd love to.
I'd love to, but I can't.
Yes, that would be great.

Arranging a time and place:
Where/what time shall we meet?
How about 6.30

What arrangement do they make?
Are they free that evening?
