A few words about St. Not an alter-ego but a little more complex than a nickname.
When email came out it seemed good to have a signature. Lots of people where I worked then developed really contrived signatures which basically told everyone how much work they did. Or at least told everyone how much time these people spent working on their signatures when they should have been working.
I began signing my emails simply with two letters but, by using St, it could either be read as short for Steve or my initials (not counting my first initial which is J and stands for James).
This presented the sort of people who have problems with things like this with problems. Becky started calling me St (pronouncing it stu like the begining of study or stutter). Liz started calling me Ste (Stee) which I liked but only when she did it. Bob used Sieve but that was a misprint. Occasionally people say 'Saint' which is wrong except when Dave does it because it is full of irony then as it is he who is that.
By the way don't call me Stephen unless you are my Grandma or Aunty Brenda (or anyone from my time in the north-east where abbreviating a name without permission was seen as an insult) or trying to annoy me.
St is a sort of virtual me I think. Me online. Not really capable of being put into spoken words but less poncey than Prince's squiggle.
I think St and Steve coexist in the same spacetime and have a strange symbiotic relationship. Which makes the fact that both of us are a Gemini quite weird don't you think?
What you called?
