A true story:
I remember hearing about an artificial satellite named "Sputnik" in Oct 1957. I remember the U. S. of A. playing catchup as it (we?) launched Explorer 1 in Jan 1958. I remember my older cousin coming to my house to be certain I was outside at the right time to take advantage of the right lighting conditions in Aug 1960 to actually see a very large gasbag called "Echo" orbiting overhead. But what I remember most: From my earliest memories, my dad rambling on and on about the physics of how jets and rockets functioned and how someday we would travel to the moon and beyond. I watched on 20 July 1969 as Neil Armstrong and Buzz Aldrin walked on the moon.
In 2002 Buzz Aldrin punched an idiot who called him “a coward and a liar” for lying about being on the moon.
Have you ever recounted an event or sequence of events only to realize that too many people thought your account sounded "less than authentic" to the extent that they thought or even said that you were a liar?
