Sorry about the evil roommates
I had the roommates from hell my freshman year. One was an anal-retentive neat freak who would routinely take over the big table in our suite lounge to do her problem sets, never mind that there were 7 other people in the suite who might have liked to spread out their own papers somewhere

The other was a born complainer who whined and whined about how not all her advanced courses had transferred. I could go on all day about those two
Even after I got my single, people borrowed my cookware
all the time. My mom had given me a very nice set of pots and pans when I went to college - I still use them - but my suitemates would borrow them all the time and then just throw them in the sink, and guess who had to wash them! I finally told my suitemates that it was fine if they borrowed my stuff as long as they washed it, but if they continued to leave everything for me to wash, I was going to keep my cookware in my room so no one but me could use it. Suddenly, my pots and pans were left clean...
