SpiderLogic helps us to understand the difference between what may be 'true' and Truth. Here's a spin on that:

I heard a story that on the morning before the Battle of Little Bighorn, General Custer ran into Sitting Bull and Crazy Horse at the Starbuck's in Sheridan, Wyoming.

Custer; then a Lieutenant Colonel, boasted to the Native Americans of the prowess and over-whelming force of the U.S. Army. The Indians best beware of a fight they could not possibly win.

Crazy Horse gave a solemn glance toward Sitting Bull and then with a sly grin aimed at Custer said: "That may be true... But the Truth is...'Not today'."

'True' may come, go and change.

Truth requires no timepiece, calendar or permission.
