You ask me about trust and I ask you about the truth.
How is trust built? With the long persistance of truth. with the courage to face your sins or problems. Years of building up trust can be destroyed with one half lie about something insignificant. How can I trust you with someting big if I know that you can lie for something small.
You might say this is not a lie, but a lie is any effort to hide or bend the truth. You might say this is not important, but if I can not trust you with one unimportant pound how can I trust you with a thousand?
Everybody lies, everybody has at one time made bent the truth a bit. So tell me who can you trust?
