Stop in for a cup of coffee
Yep, a good buddy too, we had many fun times, travels. He moved away and when I went to visit him with another good friend of his, he got into a snit about something and said I was an asshole (lol) and that was it! Really bothered me till I chalked it up as something that happens in life sometimes and it could be something screwy with him, not me.
He did in fact go off the grid, even yanked his mailbox out of the ground.
