What is the most genuine compliment someone has given you?

mine was in my 12th std. i changed schools due to personal reasons in my 12th and found it hard to cope with everything new. the Vice Principal was a family friend, she was a hot and cold kind of person to me but she really taught me how to be a better person. one day she called me aside and said ‘if marks were given for your smile, you’d be the topper’. ever since i love my smile and that’s the most beautiful and genuine thing someone has ever said to me.
