How we see ourselves is not always how others do.
It is a defining thing for the way we deal and interact with others.
Sometimes it really hard to come to terms with what we find out.
If someone takes the time to tell you things about yourself, that they perceive, perhaps we could benefit from knowing, and in turn, turn things around that might be upside down.
If we do not like what others see we can take the opportunity to change and help them to see us in a different light.
