Wait, what?

Me in the morning: Did you put away your coffee maker to put out mine when I moved in?

Her: My coffee maker? Lol, have you ever seen me drink coffee?

Me: Wait, what? Do you not drink coffee?

Her: How have you never noticed?

Suddenly realizes she only drinks orange juice in the morning and always orders frozen hot chocolates from coffee places.

Me: Oh my god, I live with a sociopath...
