<p>Without going into detail, there are occasionally cases where it’s obvious that someone set up their House preferences to try and get a single. If they pull it off, they usually contribute nothing to the House they end up in, and the active members of that House will want to break their kneecaps. Don’t be that guy or girl. That might be where the anti-single bias you heard about comes from. I can’t imagine where else, because most of the rooms in the South Houses are singles, and that adds up to about half of the on-campus population.</p>
