Haha, day to day expression typically don't make faces sore. Why? because you've been making them most of your life, so your muscles in your face are able to handle it. But! There are times when the facial muscles are pushed beyond what is usual for them and that will result in soreness. For instance if you're out in the sun all day and forgot a hat & or sunglasses chances are your face is going to hurt from squinting all day. This goes for NTs or anyone else.
