Mr

I have a middle name that only friends and family call me by and friends normally forget what my first name is but at work/ professionally I go by my first name, so despite just having just a first and middle name I've managed to separate them to a personal name and professional name. It's kinda fun

That's actually genius nobody can say anything which might get you in trouble at work because "[Firstname] shared a beer with a bear" (I don't know okay it was just the first thing that came to mind wouldn't be associated with you and you'd be fine!
