Ahhh - a Cristina question, now I know all is well with the world :)
It just simple as can be: Laurence as a baby was shortened to Lozzy as a kid, which in turn was shortened to Loz as a teenager and that just stuck. I'm Loz to all family and friends, heck, I'm even Loz to my mother!
Only my business customers and suppliers - and a lady on this site by the name of Els - know me as Laurence.
Fools rush in ....... and get all the best seats
