so in the nursey rhyme jack and jill it said

then jill came in and she did grin to see jack paper plaster
her mother whipped her cross her knee for laughing at jack disaster

now jack did laugh and jill did cry
but her tears did soon abate then jill did say they should play at see-saw cross the gate

so what the meaning of jill laughing at jack after his mom fix his head

and the meaning of jack laughing at jill after her mom whipped for laughing at him
