I don't even know what happened

I went out to dinner with my mother yesterday. She told the waitress her order and I told her mine. I distinctly remember asking for coleslaw on the side, but after the waitress left our table, my mom said "Wow! I didn't know you liked asparagus," to which I said, "What do you mean? I ordered coleslaw." She was confused and kept on saying that I ordered asparagus. I just brushed it off and thought she was crazy. When the waitress came back with our food, she put asparagus in front of me. I started panicking, but I didn't say anything of course. I didn't mind having asparagus. However, I was seriously freaking out. I REMEMBER saying coleslaw, the way it felt coming off my tongue that time. That was so freaky... I wonder what happened... ;-;
