I am asking because I am writing a short story and in one part of it, this Mexican mother is soothing her child and is being sweet to him and speaking to him in Spanish.

Please, MATURE answers preferred that happen to deal with the question! Thank you!

I learned Spanish from my Mexican mother and from my high school. Now that I'm in college, I'm kind of embarrassed that people who aren't Hispanic have a greater mastery of the grammar, vocabulary and the subtle nuances of the language, and although they might not be able to carry on a conversation in Spanish as easily as I can, I often find myself being corrected. I was hoping if anyone new of a free and easy way that I could brush up on my skills. Thanks.
