Life is complicated and, yes, there are times when it is inconvenient to tell the truth.  

It can be as simple as one of you friends asking if you like the outfit  that they are wearing (you don’t) or your boss asking if that report  will be done by the end of the day (it won’t). It can be very easy to  “bend the edges” or tell white, gray, or even black lies when we are at  work. 

Our manager training does not teach us how big of a deal this really is.
