i know sister/siblings fight and there's always some rivalry every now and then, but watching this show and watching how mary and lucy always seemed to be at each other's throats over every little thing i always felt like they were more like enemies at school than like sisters. especially how lucy always seemed to have a beef with mary usually over stupid little things. i just felt like they never seemed to get along, or rarely seemed to get along, even later on in the series when they were fighting over that stupid guy, robby, or when they first met kevin and ben. even in the one where lucy thought she was pregnant and she called on mary for support, i felt there was friction there. maybe i'm making something out of nothing, but watching this show, and being such a huge jessica biel fan, this always bothered me. also, is it true that jessica biel really did not get along with beverly mitchell, the one who played lucy?
