Young son, it argues a distemper’d head
So soon to bid good morrow to thy bed.

– William Shakespeare

Romeo and Juliet, Act 2, Scene 3. When Romeo meets and falls in love with Juliet, he goes straight to Friar Laurence to tell him his good news news. It’s clear from the manner of the friar’s greeting that there is a close relationship between the two and the friar has a father’s love for him. Greeting Romeo as "young son," the friar wonders what is troubling him that he is up so early.
