Vanessa What do you consider as "lack of tidiness"?
For example if a girl has her hair tousled, or if she is not rightly shaved, (specially if we go to beach, pool, playing sports...) . Long neglected nails...
Vanessa Do you think you would be able to make her change her way to act about her hair?
I hope, however, fortunately, this situation does not happen in my home we are coquette, however my younger sister is not so "girly" as me or mi elder sister.
Angelina because you think it will harm your sister or because you think it will harm your family in general and therefore also you?
In first place negligence in aspect harms directly to the girl, there is not second chances for first impression. To be trim has good effect in our mood. I think that women have to care about her aspect, I like my friendd, my sisters look nice, and I do not like to be with untidy people. To worry about be pretty does not make us dumb.
