If Juliet does not agree to do so then it is thou responsibility as a mother and wife to keep convincing her until she agrees.
yes, go up to Juliet an hour after the dance starts, ask her to see this guy named Paris, who is very charming and disciplined. Do talk a little about Paris, praise him in front of Juliet. Tell Juliet that he asked for her hand, and if Juliet mentions her age then let her know what I've told thou about it.
How shall I ask dear Juliet, should I tell her a little bit about Paris?
God knows what dear Juliet might say...
Are thou sure this is a good idea for our Juliet?
Yes, it is and thou shall do as told. I shall head to get ready for the ball now. Goodbye.
