It is a common assumption relating accountant with having no personality.
I disagree or am rather against this assumption.
Accountants can be serious-ish, yes.
Silently adding numbers on a calc ulator and never engage in water cooler conversation does not mean we are not interesting, it is just we are busy calculating and taking care of your money, for you.
Those blank stare you get? We just add another digit to your annual income. You are welcome.
I spent 12 hours of tabulating numbers and preparing financial reports in my black pants suit today. Then I came home to a pink room, sipping baileys and writing.
