Sumthing about my cousin sistar

Young girl born in a family,which is so nice,
shaping others tell that,she is always wise;
a very very naughty girl is what she was named,
and that little naughtiness made her so famed;

A quick sense of humor is what she is famous for,
making people happy and not to snore;
her painful work is not to be shown,
dealing the danger,all in her own;

''Be positive,think positive''this is her motto,
giving her the best husband,just like a lotto;
an young beautiful pair you were at past,
and an young beautiful pair you will be till the last;
