Mr Will.
So is his name really 'Mr Will'? Or the word Mr being used a convention in that community -because he is the eldest son or something?- or is his given name really "Mister Will". (Either hyphenated or first name Mister, second name Will).
-It's hard to imagine a toddler named 'Mr Will', but many things about their lifestyle are hard to imagine.
I prefer Imaginality to reality.
