Today, a friend of a former friend taught me an old lesson about honesty, again.
It's something easily lost.
Do anything to wrong a person, or even nothing at all, and suddenly all the walls go back up, and you get nothing from them anymore. It can take a lot of work to break down those walls in the first place... but when they're back up, chances are they're not coming down again.
And it's painful to so easily lose touch with someone that matters, even a little.
