In my opinion her decision was right because even when she had a tough life she always had her father present to be there in difficult times. Family values are more important than anything else, because in my personal value is that parents is the reason of our existence so for that reason we have a sort of invisible debt towards them. We are responsible and it is our duty to take care of our parents. I believe also, if she would have run off with Frank to the unknown world, eventually she would have regretted her act. I noticed the pressure and impatience of Frank towards Eveline. He was maybe too rough on Eveline in order to accelerate her decision; letting her the time to think of her situation and think of what is more important to her, would had been more reasonable.
She finally made the decision to stay with her parents; who at once by taking this decision she would not break the promise she had made with her mother and she would support her family instead of taking off with a total stranger. Obviously we can see that the theme of our short-story would be security and love: security I would say linking it to the fact that she is insecure of what to decide and that she doesnt know the danger waiting her outside her house. Also, if she would feel more secured with Frank in an all new world or staying with her parents c Love would be the parallel to security because she isnt sure whether she is truly in love with Frank; there again we can feel insecurity from her. Here are two scenes presented to Eveline: would it be more reasonable to decide to stay with her family or to leave with frank? If she had chosen to leave with Frank, that would had been entirely a new version of ending because there is no going back to your family after you left; you can come back but it certainly wont be the same feeling as before. An escapade with Frank could have been terrible for Eveline, because it would had been a decision she didnt plan but only from "night to day" or "south wall to North wall".
