1. Thanks so much for inviting me, but I already have plans. We can do it another time.
2. I'm sorry, but I can't go. I have to study for an exam tonight. Maybe next time.
3. Unfortunately, I have to decline. But thanks for the invitation. Another time perhaps.
4. I can't go tonight because I'm busy. Can we do it tomorrow instead?
5. I appreciate the invitation, but I can't go. Can I take a rain check?
