person A: I told my mom that I didin't want to be in compsci anymore_comma_ because I was really miserable. She said that I should do what makes me happy.
person B: That's good advice.  If you're not happy doing something you should spend time thinking about what you'd really like to be doing.
person A: Thanks. My mom is usually very strict_comma_ and I thought she would be really upset.
person B: Even if she's strict she's probably doing because she wants what's best for you.  And she'll probably support you no matter what you decide.
