Equal but not the same

With a flower build a house,  a guard dog in the form of a mouse

Drive a nail made of thread, sew with a needle formed from the mattress of a bed

A father now a mother, a sister turns into a brother

A doubt now devout, nature turned inside out

When does a woman become a man? Both cooked in the same pan

The recipe differs just a bit, one with sugar one with grit

Is the cake jealous of the meat? Does the potato envy the sweet?

With our appetite both we eat, without either the meal's not complete

All desire what they are not, so with a lie a delusion is bought

Both grass and stones deserve respect, neither gender without defect

So if a flower serves for your abode or a mattress point for clothes sewed

Use thread that's nail hard and let a mouse be your guard
