Hoy hay una fiesta en casa de María. Es el cumpleaños de su hermanito. Pero qué sorpresa se llevan todos cuando, de repente, de la boca del pequeño Teo sale una palabrota. ¿De dónde habrá sacado eso que suena tan mal? Entre todos encontrarán una forma muy curiosa para evitarlas.The latest story by Elisenda Roca, Do Not Say Bad Words, illustrated by Cristina Losantos, is aimed at those early readers who absorb all the swear words and curses that adults say. They imitate them, because they think it's funny or it makes them feel grownup. They still don't know that these bad words are not polite and that it is better not to say them because they can offend people. This story places a focus on grownups in the family who swear a lot, and we help children understand why theyshouldn't copy them.
