Guy acting sexual

Grace

This guy in my ELA class sits in front of me facing me and, normally he'll just annoy me. Mess with my book mark or steal my stapler, but today he rubbed his feet on mine. I got uncomfortable real fast so I moved my feet away and he just kept moving his feet to me. I don't know what to say about this because he's known for beating people up. I can fight but he towers over me. I'm kinda ... scared I guess.
