Jehovah's witnesses at my door

today a jehovah's witness came to my door. I had never seen them doing this in person before but  also didn't know much about their beliefs. All I knew is that they believe only 144,000 can be saved, and that they have a special translation of the bible they use. I know I had a pamphlet from Jo Cook that had the four spiritual laws and scripture to back it up with. The woman told me a common thought among Americans about armageddon that I had never heard before, so I tried to give her the pamphlet with scripture in it but she wasn't very nice about it haha. She told me that if I wanted to talk to her about anything, I should come to her door, then she quickly walked off. I felt so awful that I was not able to quickly tell her where in scripture she had it wrong (i was literally shaking). I don't feel sorry for myself though, I had every opportunity to study and memorize and to learn what they believe. If you are reading this, take this as a warning, because i never thought i would be in this situation. I will tell you this though, I will do what I can to make sure it never happens again.
