Do you want to use Spanish at home? Commands are very common and well used in everyday Spanish.
What are commands? Commands are used to tell someone to do something in a direct manner. It may sound a little rude for an English speaker but they are not rude and they are very common. Politeness is determined by the tone we use.
Teachers and parents use more commands in every day life so it is a good idea to start using them at home when possible.
