I think I was just told off!

I went to put the garbage out on the steps last night so that on the way to work I could take it to the dumpster. As I opened the front door Kellie started marching out, I was able stop her and I pointed and told her to get back down the hall. She gave me a look, turned around and marched down the hall to the bedroom, meowing all the way. It was so funny, I felt so told off. I wonder what she told me in her cat language?
