SRS, Virgil found roommates completely unreliable (especially about washing dishes). They are, however, likely to develop odd food preferences - Vegans, coffee/tea snobbishness, homemade beer, etc. The worst offender was a dad (divorced, of course) who would sponsor trips to Sam's Club to buy huge bags of candy, chips, cookies, just a mountain of junk a couple times a semester. One guy was on the edge of scurvy because he decided that it was just easier and cheaper to eat only mac and cheese (he got a free bottle of multivits and a lecture). None of this, BTW, is a male/female thing. These kids, after the dorm, seem to think co-ed housing is normal (I guess it is. Certainly now, at 30, he has several close female friends who were once apartment-mates.)
