Braceface Season 2 Episode 14 Home Alone

David takes Helen on a long overdue vacation. When the housekeeper hired to spend the week with the kids quits unexpectedly, Sharon elects herself as the 'surrogate mom' to demonstrate to her mother that she is responsible and deserves a later curfew. But first she becomes 'hyper-responsible' and, then in an attempt to undo her 'wet blanket reputation', throws a party. Meanwhile, Sharon, Adam and Josh start out squabbling--but by the end of the week, they have united. Sharon discovers both a meaning for the word 'responsibility' as well as a deeper level of sibling closeness.
