"Julia is old."
Translation:जूलिया बूढ़ी हैं।
That sentence forgoes the honorific. You might be of the same age (or older) than the person being referred to in which case you don't use the honorific (unless you want to be formal). It might also be a situation where using the honorific does not make sense (Eg: मेरा कुत्ता बूढ़ा है - My dog is old) or you might be rude/disrespectful intentionally.
