Gross Tenants

So I am back in Rexburg and moved into my apartment... the exact same apartment we had before! So I heard this horror story from the managers of my complex about the tenants who lived in my apartment over the summer. Apparently they either didn't know how to work the garbage disposal, didn't know there was one, or it was broken and they never said anything. So apparently by the end of the semester they had 4 months worth of crap sitting in the garbage disposal!! The good part, I have a brand new garbage disposal! So after hearing this story I was a little worried about the cleanliness of the former tenants.... :/ So when we got here the bathroom sink wasn't draining very well. I made the very unfortunate decision to look down the drain! I pulled out the largest hairball of my life!! I nearly vomited right into the sink! My mom had to clean it up for me. SO now I am very nervous to inspect the bath tub drain...
