I've been harmed too many times by people who were habitual and gleeful liars. I learned, even as a mature adult, that lies can do a lot of damage. Even "little ones".

I think every child tests boundaries, and teenagers especially have a reputation for routinely lying (although generalizations are something I tend to avoid).

I'm like you, Discom; as an adult I formed a very powerful dislike of liars, especially the intentional ones. Initially, I forgave them. But as it went on and did real and lasting damage to other relationships I prized very highly, I came to really resent it. And I do wish I had confronted those people openly and in public much sooner, and very firmly.

I do not feel bad about my resentments and my strong dislike of liars. I think they do not deserve any form of trust, and that they are capable of anything.
