Are teachers ever this joking?

So I've spoken a word or two of my science teacher before, but today was insane! I didn't greet her, because I was still just a little upset about yesterday.. and so she jokingly ignore me and acted disgusted at me. I went around to sharpen my pencil and she kept speaking about DB and I, saying that we just stopped right in front of her and hugged and that I would speak to him and not her. When she was sitting at her desk, on her desktop, she said that I would need her first before I would ever need him. Today was just the most different. Dang! I forgot to ask him if the teacher commented on us today like she did with me..
