I couldn't have put it better myself
And this is *exactly* my point

What *you* choose it to mean may not be what someone else chooses it to 
mean, this is why we need to step down a level and think about what 
exactly we *do* mean when we name a concept.

Anyone who thinks that the names we give our concepts are not important 
is ... deluded.

What does 'Employee' say to you?
Now what does 'Person' say to you?

Think about what these words mean to someone who may not be in your head 
but has to maintain your system.

IMHO the names we give things is the most important part of the system 
documentation
