Hi. I think I already know the answer. Here's a basic example of my question. In English: Some people like to eat at home. They cook well and a lot. En español: A unas personas les gusta comer en casa. Ellas cocinan bien y mucho. My question: Do I have to use "ellas" here? I think I do because of "personas." (But my English-speaking brain is looking for the girls when I use "ellas"!) Sorry for such a basic question.
