My Friday night routine:
1.) Come home around eight. Spend as much time in the library as one can tolerate in the hopes that by the time I return home, my roommates will have already gone out (in case they should *gasp* invite me to tag along).
2.) Invent some project that requires I stay home, in case one of my roommates should find me anyways.
3.) Throw dinner in microwave, retreat quickly to room. Any non-microwaveable dinner takes too long to prepare, and increases the risk of exposure.
4.) Sit in room, surf the internet. Convince myself that by being isolated, I won't become just another silly member of society.
Note: On particularly wild weekends, I may watch a torrented movie. Movie theatres, once again, require a venture into the public.
Anyways, I do find some comfort that many of the experiences I have read about on these boards are so similair to mine. It gives me some hope that their may be light at the end of the tunnel!
