I don't think I'm going to tell anyone why I switched schools. I'm afraid of what they might say.
What do you think they would say about you switching schools?
Some would feel betrayed while others would ask why.
It's understandable to not want to reveal everything about yourself, but your motivation for doing so shouldn't be driven by fear. You have a right to do things that are best of you regardless of what others may think or say.
I wish I had the same confidence.
If you're not comfortable with disclosing why are you switched schools, then don't. It's OK to keep some things private, especially when talking about them only serves to satisfy other people's curiosity.
