The question of "which" comes if you have "confusion". The origin of confusion comes if you are not happy with the first or may be you like both!!!
As a matter of fact, anyone who falls in love for the first time doesn't have any confusions as the one feels the first love is the best. But later, may if the first crush fails, that impression of failure remains for lifetime.
For those, who falls in love for the second time....feels that they can forget their first love. But whenever, they have any bad experiences or any short time breakup with the second love...then those impressions of first love failure keeps on pinching them with extra impact.
So it makes fear of failure...thence by, CHOICES and OPTIONS....Convinced??
According to me (Choice 1 is backup) and (Choice 2 is trail)....
In my case....i would always prefer the choice which could be a trail.
