Reality of people | Motivation about life | Motivation

In today's cruel world, mostly people have more than one face. yeah it is reality. these people use their faces according to the need of the situations.
They show their good face on the situation which gives benefits to them, they show off that how much are they good.
But in the other side they show their bad face on the situation which doesn't give them benefits, they mostly ignore these type of situations.
and I think these type of people do not have feelings and emotions... they simply use the situations and also the people.
And we should not believe such type of people.
