My Name is Kimberly!!!

It should be no secret to anyone reading this blog that my name is Kim. Kimberly to be exact. The only people that call me Kim are my family members and close friends. That's it. When I introduce myself to anyone, I say "Hi, I'm Kimberly, " so why is it that when I tell people EXPLICITLY that my name is Kimberly they feel the need to automatically shorten it to Kim. There is nothing in "...my name is Kimberly..." that says I give you permission to call me Kim. That burns me up. I absolutely hate when people take the liberty of calling me Kim. Stop.
