User blog:RadicalPatMan/Why was Luan considered a mean sister?

I know this whole mean and nice sisters trope is dead and all but still I'd like to point this out: why is a nice fun lving girl like Luan considered a mean sister and lumped in with Lori (who forced Lincoln to go on a double date so thar she and Bobby could get back together), Lola (who pranked Lincoln just because he ignored her), Lisa (who made two of her siblings bald), and Lynn (who accused Lincoln of bad luck).
