I doubt the children had much to do with this, consider Laura's apathy for the silly boys she dances with, or Laura's desire to end the party on the account of Scott, or how Jose felt it was too late to call it off, rather than feeling like she would be personally upset to call it off. These parties are the adults ideas, but Sheridan likely has trouble accepting such a vapid pass-time as worth while, her ego is a mess, because its such a pointless endeavor, and that's why she must convince herself that it's the children's idea.
