I'm still confused.

I am having somewhat the opposite experience with the shared roommate spaces that I had last semester.  When I moved in to my last apartment, it was one girl's second year in that apartment.  Apparently the old roommates decided to leave several items in the apartment, such as ridiculous amounts of canned and boxed food, toothpaste, bath products, etc.  At one point we had six bottles of shampoo in the shower.  Everything was in excess.  

I'm confused as to why none of my roommates leave their toothbrushes, toothpaste, face wash, and other toiletry items in our bathroom.  Do they think this is still dorm life where you can't leave things in the bathroom?  I don't get it.  We have a large cabinet under the double sinks in our bathroom.  I keep my mouth wash, toothpaste, face wash, moisturizer, and a few other items under it.  I'm taking up about one third of the available storage space, yet there is NOTHING else under the sink besides toilet paper. 

Then there is the kitchen.  My roommates also keep just about nothing in the fridge.  Last semester our fridge was always overloaded.  My roommates would sometimes buy things and forget that they were in the fridge.  It got to the point where I would start throwing some of their forgotten food items away without saying anything, such as fruit and produce, because they were starting to go bad.  

Although all of these things are strange, they are not problematic.  However, there is one thing that is somewhat bothersome to me.  The two girls who are friends from their hometown always use paper and plastic plates and silverware. WHY?? We have so many plates and cups and plenty of silverware.  It's so wasteful and bad for the environment. Oh well, to each his own.
