I spent two years as an elementary school teacher assistant after graduating from university. That's not where the pen name came from, but I do like to establish credentials. And I need 140 characters to complete the post.
I worked for a newspaper after I grew tired of teaching little children the intricacies of running and jumping. The company had a naming convention for employees - the first six letters of your last name and the first letter of your first name.
- Schule (missing one letter);
- G (missing three letters informally and six letters formally, with a repeating r in there);
It's been a handy and easily remembered sobriquet since then and may pop up on the internet in certain places. I respond to "you", "hey" and Greg.
Such a boring story, but that is what a lack of imagination will do for you.
