I guess when people already have some perception of you, even before you can answer their query, they have probably sketched a plot of how you might answer and how they are going to reply.
There is no use trying to give an impression when people have already put that judgement on you way before you are given any chance to win their heart.
This judgemental attitude is difficult for some people to get rid of. Maybe only someone superior can talk to them and let them open up their mind to have a change in perspective.
However, I do believe that somehow...
There is always hope for a person to change.
There is always space for acceptance.
There is always room for improvement.
And there is always time for a heart to heal.
