Please check the following paragraph.
This is my mother, and she is a Pisces. She always hides her feelings, so itís very hard to know what she is really thinking. But she can easily understand what other people think and how they feel. If something worries me, I will tell her about it immediately. She is a good mother.
Seems okay to me.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
