I knocked on the door again and she yelled for me to go away saying she didn't want to buy anything. At this point I understood what was going on. As it turns out, for the past couple days she's been getting salesmen knock on her door and try to sell her something. We talked it out and is clarified that I was actually her new neighbour an not someone trying to sell her something. In the end everything turned out alright and she actually brought me fresh baked cookies later on. They were good. Anyways just wanted to clear up that it was a misunderstanding and she didn't mean any harm.
