Always telling truth is one of the most important virtues. Personally, I believe that for building relation between two people, always telling truth is the most important thing. I feel this way for two reasons, which I will explore in the following essay.
To begin with, any people keep faith on a person who tells truth always. Trust is the most important matter in any relationship. Untrustworthy people is unfit for any relationship. Trustworthy peoples are very unlikely to break any commitment. Hence, telling truth makes people trustworthy which leads to a healthy relationship. My personal experience is a compelling illustration of this. One of my friend was a bloody liar. He always told lies to her parents in every silly matters. Therefore, his parents had started to loose faith on her and they always engaged in a quarrel with him Hence, his relation with his parents was going to downward.
Furthermore, telling truth always keep away people from dual expressing personality. In the real life, we can see many persons are pretending not like himself to impress another person. But it is hard to pretend like others for a long time. So, whenever that person expresses his own personality, another person may loose interest on him. Hence, the relationship is less likely to last long. For instance, a poor friend of mine did relationship with a rich girl. Whenever that girl knew that my friend was poor, she left him
Telling lies is very harmful for any good relationship. This is because it breaks trust and encourages people to express dual personality. 
Always  
telling
  truth
 is one of the most  
important
 virtues.  
Personally
, I believe that for building relation between two  
people
, always  
telling
  truth
 is the most  
important
 thing. I feel this way for two reasons, which I will explore in the following essay.
To  
begin
 with, any  
people
  keep
 faith on a  
person
 who  
tells
  truth
  always
. Trust is the most  
important
 matter in any  
relationship
. Untrustworthy  
people
  is
 unfit for any  
relationship
. Trustworthy  
peoples
 are  
very
 unlikely to break any commitment.  
Hence
,  
telling
  truth
  makes
  people
 trustworthy which leads to a healthy  
relationship
. My personal experience is a compelling illustration of this. One of my friend was a bloody liar. He always  
told
 lies to her parents in every silly matters.  
Therefore
, his parents had  
started
 to  
loose
 faith on  
her and
 they always engaged in a quarrel with him  
Hence
, his relation with his parents was going to downward. 
Furthermore
,  
telling
  truth
 always  
keep
 away  
people
 from dual expressing personality. In the real life, we can  
see
  many
  persons
 are pretending not  
like
 himself to impress another  
person
.  
But
 it is  
hard
 to pretend like others for a long time.  
So
, whenever that  
person
 expresses his  
own
 personality, another  
person
 may  
loose
 interest on him.  
Hence
, the  
relationship
 is less likely to last long.  
For instance
, a poor friend of mine did  
relationship
 with a rich girl. Whenever that girl knew that my friend was poor, she  
left
  him
Telling lies is

because
 it breaks trust and encourages  
people
 to express dual personality.
