Another brazilian expression gets funny when in english. "Take your littlte horse out of the rain" states that you should not think about it. I.E. You tell your little brother that your are going to the movies with some friend and you notice that he would really like to go along, but you do not want to take him so you say right away: "but you can ake your littlte horse out of the rain". In portuguese, is "tire o seu cavalinho da chuva".
