Translation:You are not twenty-three years old.
I answered 33, duolingo says that I have a typo and gives me the green anyway.
The owl is just too soft-hearted! (makes up for all the times you were wrongly dinged eh?)
I wrote twenty three and got it wrong, needs a hyphen?
Nevermind I just saw I had your instead of you
Generally: does this sentence say "you are not..." (might be older) or does it also imply "you are below..."
