¿Se porta bien el perro de tus vecinos? - No, se porta mal, se come mis flores.Does your neighbor's dog behave well? - No, it behaves badly. It eats my flowers.
Si se porta mal con ellos, no me extraña que ellos no quieran luego hacerle favores a usted.If you behave badly towards them, I'm not surprised they don't want to do you any favors.
