Dramatic Tension between Romeo and Juliet

If a day is life, as Friar Lawrence says it is, then life for Romeo is the enemy of love which exists in its purity alone, in the little death of private darkness. Hidden in that darkness, it can shine for the perceptive lover with a brightness exceeding that of heavenly bodies. Under Juliet’s balcony, Romeo emotes:
For Friar Lawrence, the day is life since night for him is a period of no activity – only sleep which is a kind of “little death”. But for Romeo, the night is life despite the darkness since it is the only time when he and Juliet are together and can express their love for each other.
Juliet and love are Romeo’s life, and there is no light but Juliet and love. Romeo cries out, “O blessed night!” A scene follows wherein Friar Lawrence salutes and blesses the morning, but when it is Juliet’s turn to bless the night that she and Romeo have had with each other, she cannot admit that it is almost day. Dawn, to her, is some mistake. Day, if it has really arrived, will be as dead to her since it only means separation from her new husband. Tension is created due to Juliet’s refusal to accept the fact that day has set in and the lovers must separate. When Nurse, proves that darkness is indeed over, Juliet sighs – “Then window, let day in, and let life out.” For Juliet, love has become the only light – something shining of its own power and volition, which needs night as its background in order to be recognized. Also, Shakespeare makes comments about the light and darkness because at the time it was performed they did not have lighting and so they are included to let the audience know what time of the day it is. (You are pointing to production lighting, which may disrupt the literary analysis of “light” in the foregoing sentences. In that case, don’t you think, it is kind of off-tangent?”)
When&nbsp.Romeo descends the ladder, his young wife asks the poignant question, “O thinkst&nbsp. thou that we shall meet again?”&nbsp. The irony of it all is that they will never see each alive again.&nbsp.&nbsp.
