On the issue of whether it matters- maybe it's an NPC thing & we can agree to disagree. Any public figure reflects on the organizations they are in- the same way I am a representative of my family, my company, my region, etc. Psychologically people want to group or bucket individuals so they can better understand them. No, most random people walking down the street won't know that Britney's a Kappa or Rachel's a Phi Mu, but if someone hears about several public personalities/figures who are in that org, they'll start forming an opinion. The same way you would if you meet several people from one country or type of interest. There are always outliers and the most public ones don't always represent the whole, but that's the way things work.
Anyway

Britney is cracking me up. She has added so much comic relief to the show... couldn't stand her when Monet was on, but love watching her now. Did anyone else have a few WTF moments when they showed Britney & Lane's hometowns, and both families appeared to forget that Britney is engaged?? Her mom mentioned it as a reason she was holding back, and a second later said that she would love to have Lane as a son-in-law. Umm... okay, great vote of confidence for her fiance right there! It's tv and it may have been taken out of context or prompted as a joke or hypothetical, but...
Glad to see Kathy's gone. Every time she does something clumsy or ditzy my husband and I are thinking "she's a SHERIFF??" (great example of my point above

) Should be interesting to see if the brigade sticks together or not. I hope they go their separate ways. And go Britney for HOH!
