yeah, look, it is one of those invisible qualities... 'he sees nothing and at this distance' something like that from Alice in Wonderland... but I know what you mean.
I saw a Thai motorcycle gang friend who I had not seen in many years. I had given him money for an operation to remove a tumor 20 years earlier - one of the first things he said to me was that he was happy to see me because he finally had some money and could pay me back... is that integrity? I have many stories like that, including family members paying me back.
I am more likely to get paid back by a Thai than a farang.
