"I just need to know if its possible for two people to stay happy together forever." -JUNO
As I watched the movie for the second time, this line just inadvertently hit me. I have had a couple of questions similar to this.
How do we know that the person we are supposedly "in love" with is the right one? How do we know that the relationship will last for a lifetime?
Its a very obnoxious thought specially when we only have one lifetime to live. - one chance to make things right, to fall in love with the right person, and to spend "forever" with him/her.
All we could do is waste precious time, gamble, and hope for the right one to just come and take our misery and doubts away.
