You made your bed now you must lie in it.
Tú te lo guisas, tú te lo comes.
You can't look a gift horse in the mouth.
A caballo regalao, no le mires el dentao.
You win some you lose some.
A veces se gana, a veces se pierde.
You scratch my back and I'll scratch yours.
Hoy por ti, manaña por mí.
You can't teach an old dog new tricks.
No hay quien enseñe trucos nuevos al perro viejo.
You can't judge a book by its cover.
No fiarse de las apariencias.
You are what you eat.
Somos lo que comemos.
