The future is in your hands: Can we predict what someone will say next based on their hand gestures?

Yesterday I visited a friend. I just sat down on their couch, when my friend began to ask me, “Would you like to…” From just these words, I didn’t know how the question would end, but I saw that my friend was simultaneously gesturing as if she was drinking something. Because of this, I could already predict that my friend was about to ask if I wanted something to drink and could begin planning my response (I was thirsty, so definitely “yes”!). This way, I could respond quickly and without hesitation to my friend’s question.
