Crappy Roommates

Sometimes I wonder if I'm the crazy nit-picky one...I've shared rooms and had my own room, and either way I seem to encounter a few nutty ones along the way.  The only person I never had a problem with was my other fellow pre-med roommate.  We were civil to each other and our schedules were such complete opposites of one another that we never had any sort of conflicts (or none that we mentioned to one another).

I've had

• A dorm roommate that brought friends that would use my laptop until I password-locked it.  The roommate was cool but as for her friend - really?  Where was your mom when you were supposed to learn manners?
• A housemate who slept with her boyfriend on the couch fold-out bed almost every night during the school year.  She finally stopped after a while.  What I didn't like most was that there was basically an extra person using our kitchen/bathroom/living room, but not contributing any rent.  
• A landlord who seemed nice and put together at first, especially because she ran a nursery home out of her house, but turned out to be nutso.  She did yoga and let the kids watch Baby Mozart and I don't think she cuddled her infant charge much or really played with the other kids, unless you count gardening while they waddled around the cul de sac as "playing."  I also could not for the life of my geeky self figure out how to connect to her Airport wi-fi router, not even with Apple techs, and her router was in her colon irrigation office, so I only used internet via Ethernet late in the evening.  She also ate my entire, brand new tub of Dreyer's ice cream in the time it took me to pop into the office one Sunday to check e-mails and take care of other things via internet.  The last straw was when my landlord's fully grown daughter moved in with her three kids after some family drama.  If it wasn't for her nutso self, I wouldn't have minded staying there - the kids were really cute and it was fun playing with them on a day off and in the mornings, but I couldn't stand her anymore.  
• A landlord who seemed like a really cool hippie...until her girlfriend moved in and they started planning their hippie screw-the-legalities wedding.  It seemed like my landlord was footing most of the bill for this event, and when they argued about it, I felt reaaaally awkward cooking my dinner right next to them.  She would also have near meltdowns over something really small - like when Bubbles the cat lost her collar one day.  I think Bubbles actually avoided my landlord completely - the poor thing was really skittish.  

I think I'll try my hardest to find an itty bitty studio or 1 bedroom in the future...Some place where I can bake and cook any time I wanted to, not have to listen to crayzee couple spats, and can actually enjoy being in "my place" as opposed to feeling like I'm hiding out in my bedroom or avoiding the house completely.
