Always know what you are talking about. If, for example, it’s a movie, then you should know the rating of the movie (G, PG, PG-13, R, NC-17). If you’re underage and you’re seeing a more mature movie, don’t mention the movie unless your mom asks. Just mention the type of movie, like comedy or thriller.
Working hard in school demonstrates that you’re responsible and mature. The more you can do to meet your academic obligations, the more likely your mom will be to give you what you want.
If you find yourself getting overwhelmed, frustrated, or angry, give yourself a few minutes to decompress. This should keep you from saying something you don’t mean.
