A Jehovah witness came to my door today.

Around 10am I was awoken by a Jehovah witness and her grandkids. I had just woken up from a long night of crocheting so I was a bit dazed and wasn’t really taking in every thing she was saying. She handed me a card about how I should read the Bible. At the moment I didn’t know she was Jehovah witness, but something told me to ask. She said yes and asked if it was a problem. And I told her that I don’t agree with Jehovah witness and I don’t believe they are essentially Christians. Her facial expression became serious and she then try to debate me about my beliefs, but I was to out of it to engage so I told her that I’d rather sleep. She told me, fine, she’ll be back Friday. I was extremely tired and nodded my head, essentially agreeing with her. Now that I have time to think after sleeping for one more hour and I really don’t want her back. On Fridays I’m the only one home because I’m in college and it’s the only day off. I don’t want to not answer the door as I basically told her to come back and that would be rude. What do I say to her?
