I have never been to a Halloween Party and that's why I invited you to go. Never mind if you're busy that day. We can meet for dinner later. It's my birthday next month and I'd like you to say yes during that time if I ask you out, ok?
I never been to a Hollaween Party so I invite you to go along with me. Never mind, we could arrange another dinner date and please don't say no again for next month is my birthday!
