In 7.4 the subject of the sentence is always placed at the end
me gusta el gato.
el gato is at the end. This is true of every sentence in the lesson except when then make a person the subject
Miguel me gusta.
Then the subject (miguel) is placed at the front. This doesn't seem to be discussed anywhere. Are there any rules for this? Can the subject always be placed in front as well?
el gato me gusta?
me gusta Miguel?
