I have a name that wasn't unheard of in the 70s, it wasn't popular but it wasn't a complete rarity.
A shortened version of my name became Very Fucking Popular in the 00's but was used before then.
I have never been known as the shortened version of my name, I do not introduce myself as the shortened version of my name. The only people who have ever presumed to use a shortened version of my name are men both professionally and personally who are introduced to me, and then, for some reason, chose to call me by the shortened version of my name.
I obviously correct anyone who does this.
And I have taken to calling anyone who does by a shortened version of their name. No matter how stupid it sounds.
I was going to finish my post with a; 'But why do they do it?'.
I know why they do it.
They need to stop it though.
It's very annoying.
