QM - I was getting really confused there for a second - because I've only ever known you as your aforementioned abhorred nickname without the 'y', it's how you introduced yourself to me!

We were contemplating Will - I like one syllable names or those which are unable to be shortened.

I also know quite a few girls whose full name is Charlie.

There will always be some people who will invariably stuff up whatever you call him whether it's short or long, common or uncommon, so go with what you like!
