Jack and I used to exchange messages regularly back in the day, and on very friendly terms.
We used to message back and forth via email, until one day, he disagreed with an analysis I had completed on a section of a photograph taken in Dealey Plaza.
He went all moody on me, saying that I shouldn't be analysing photographs of Dealey Plaza, as I had never been to Dealey Plaza.
I replied by asking him when he was going back to the Moon.
He never spoke to me again.
