I tried to comment on a friend's journal earlier, and it said I was banned! WTF?! I've never had any problems with this person before, so I'm hoping it's just LJ being weird. *fingers crossed*

If I Friend someone and they Friend me back, shouldn't that make us Mutual Friends?
I just checked on a friend's LJ, to see if she'd updated or anything, 'cause her LJ is sem-Friends Only, and I could see the last entry just fine before, only now I can't. So, is there anything that I can do on my end to fix this or what?
