Living you life honest in every aspect of life is the standard. I manage to have this integrity in the connection with other people. What I find hard, is to be honest about the difficult circumstances I my self are in. I always think there is hope, in every relationship and situation. I give people around me new chances to do good. 
So many times this has hurt me... And I lie to myself, and say things are better than they are. But it is a blessing when people change their ways. 
The difficult part is to be honest with myself, when the truth hurts!
