I didn't say that, if fact if you look close you might see I actually said "Not necessarily all that worse than the other cast members".brasca wrote: Yes, she's a terrible person for wanting to enjoy sex.
What struck me when I re-read Peggy's introduction and her appearances following was that she seems (to me anyway) a lot more self-focused (at least in intimate matters) than I remembered, and actually a bit closer to Matt-like than I recalled her being.
What I would call kind of terrible is breaking up with her fiancee (the final straw apparently being her wanting him to do something that he wasn't comfortable with, which is it's own kind of awful), and immediately moving on to the guy at the next table, and then on from there. Add to that the fact that Jim apparently was pretty in love with Peggy, since after all that he still wanted to try and patch things up, even considering to try and do the very thing he wasn't comfortable with in the first place.
