He was a Bostitch (staplers) salesperson for a number of years. Family lore says he was really proud of his job. He even won salesperson of the year. (I have one of his staplers that still works, and which I use today.) Then they fired him, and the tale goes he was really torn up about. Later, he had a flower shop with my grandmother and some other crafty-type businesses.
Being fired, especially the first time, is devastating. Thanks for sharing this example.
