Answer:

I changed my attitude about how I react initially towards a person whom I have no absolute idea about their identity.

I become more aware of how one's personality could not be simply evaluated based on physical appearance.

I was surprised about how someone could look so appealing and innocent and yet they could be the most vicious person without you knowing about it.

I felt that I've been more optimistic and sensitive of how other people felt, and it really shapes you to be a more decent human being.

hope it helps u
