Names.

Names are important to me.
For example, the name Jake. I have never met any decent guy called Jake. One called Jacob. Zero called Jake. They are all dicks.

And spellings of names are important too.
Let's take Nicole as an example.
Nicole is Nicki's full-name. But her name is Nicki.

I become distressed when people write the name 'Nicki' with any other spelling than 'Nicki'.
It's just wrong.

Nicky is unacceptable because Nicky is a boy's name, and Nicki is not a boy.
Nikki is unacceptable because Nikki is a porn-star's name, and Nicki is not a porn-star.

Only Nicki is correct.
