4. Clipping nails (and toenails) just about everywhere in your apartment, and only sometimes cleaning up the remains.

7. Make yourself burp a lot until you almost accidentally throw up.

10. Spending inordinate amounts of time on the toilet, just because it’s sweet and perfect "alone time," even if your legs eventually go numb.

12. Pulling out the long hairs that get stuck in your ass crack after a shower.

15. Sprawling out naked on your bed in the world’s least glamorous/flattering position, and browsing around online.
16. Catching yourself in the reflection of your computer screen and realizing that you have about 7 chins and your resting position is “mouth slightly open.”
17. Planning exactly how you’re going to get to a remote area to scratch your ass which is itching like you’ve never experienced before in your life (and considering walking into a side alley to scratch because you can’t make it all the way home).
