My thought about Sales

I like doing sales.
In sales line, you will be able to see the trueself of person that you are dealing with.
There are people that nice and like you so much..
At the same time, there are people that simply show their dislike and irrespect towards us, just because of our career, and the emotion come, even before they know us..

Is this something good?
People that we are dealing with in sales, are the trueself, they do not need to sweet coat themselves to us. When you are in sales line, friends have others friends and only if they like you, they will continue to-be-friend with you.
Respect is simple. Simply felt offended when meet people that shows irrespect..
