“'Yea', quoth my husband. 'Fall’st upon thy face? Thou wilt fall backward when thou comest to age, Wilt thou not, Jule?' It stinted and said 'Ay.'"

Nurse says, bursting out in laughter.

You were a maid in the Capulet's house. Juliet secretly had a crush on you, and her face turns pink when Nurse says that. You were cleaning her room, Lady Capulet and Nurse in the room, speaking about Paris' marriage proposal to Juliet. She didn't want you seeing how pink she was from Nurse's words- Nurse was talking about how when Juliet was young, Nurse's husband was saying that when Juliet's older, she'd be having....sex.

"And stint thou, too, I pray thee, nurse, say I."

Juliet says, embarassed, not wanting to look embarassed in front of you.
