Just LEFT-CLICK the mouse to toggle through an animation on Do's and Don't's of using the hallway. Press R to see an animation again. Show this to your friends who lack hallway etiquette! I have witnessed all of these issues abundantly in my school hallways, and they are some of my pet peeves! If you are also annoyed by this (or if you are a perpetrator) I hope this animation will be useful for you!
