In my opinion, the student body at Mines seems to have a problem with defining personal space and pigheadedness, particularly on the main sidewalks between classes. I have been run into countless times from lazy students who refuse to respect their half of the sidewalk and move out of the way. This problem is greatly intensified by the presence of snow. The limited walking space created by snow barriers leads to an excess number of physical collisions because students are adamant about standing their ground and not moving to their half of the sidewalk. I understand that they maybe mid-conversation with a friend but I believe it is the respectful thing to move either in front of or behind the person you are walking with to avoid running into someone else.
