For example this one time me and my guy friend (at the time) were in the hallway waiting for our class to start. It was just me and him..he was standing/leaning on the lockers and I didn't want to sit on the floor because it was dirty, so I opened this sliding glass door shelf Thingy (a place to put trophies and bulletins and such) and I sat in it. Then he smiled at me and started shaking his head.
Another time I was in class I was biting my lip and I looked at my other guy friend and he was already smiling and shaking his head at me.
What the heck? Lol
