what kind of friends' filters do you have? some people have filters they use because they have a million friends and only want to read some peoples' journals and not others.
i use two filters. one for people i'm not romantic with...oddly enough, there was a period there when it seemed everybody had an LJ. i have another that is only really close friends i've met in real life.
the funny thing is, i never used them until i got a divorce and my ex-wife broke into my account and friended herself. i don't pay attention to who is on my friends list so there were a few days where she trolled through my account printing out my flocked entries about her. i know that using a friends filter wouldn't have necessarily kept her out (in this case it would have) but this little incident made me realize i needed to be more discriminating.
also, working 50 hours weeks, plus an extra 1-2 hours a day commuting SUCKS.
