What Did Rachel (Niece of Abraham) Do Wrong to Be Punished by God?

[mythociate]

I mean^*, we know the punishment--barrenness while her less-attractive sister had three kids with her husband--but what was the sin for which she claims she was judged?

I think it was the pride which naturally accompanies 'being so much better than someone nearby.'

^*And I know I'm saying 'I mean' an awful lot at the beginnings of topics, but ... I mean ( ) I don't see anything 'wrong' with it
