I understand. You have raised your children in a different time than we did hours. That's all I feel I should say since we have very different ideas.
As far as their jobs, Gabby had worked just recently at a new job saving for her trip. I haven't seen where Brian worked.
We all love the idea of a couple going out and traveling the country. Gabby was apparently ready. Her car, her money. As for Brian, seems to me he was depending on her. Her van, her life, her money.
And when he returns home in HER van, he is back to mom and dad's with them feeding him and paying his rent. Something wrong with that picture.
I am surprised that their first priority wasn't to save to get out from under his parents care.
In any case, i hope they find Brian soon.
