Knowing the true personality of others is difficult

Sometimes we might think that it is easy to judge others and pretend to know others very well. However, knowing the true personality of others is difficult because what we are able to see from appearances does not give us the total picture of a person. Even if we have known someone since we were young, it is still hard to learn everything about that individual since many characteristics may be hidden deep inside. Therefore, it would be really wise and safe from our side not to jump to conclusions.
