You are practically right but for most filipina wives, balikbayan box is just a way of thinking your family back home. For me, it is also our family's way of lambing or to show fondness and affection. My little 3-4 year old cousins told me, ate, if you will send me chocolates and dolls I will be very good like angels in heaven. I was touched with their magical words ehehhehe, i feel how desperately they want it and found it is cheaper to buy here second hand dolls so why not? I used to send cappuchino coffee to my Mom as she love it and I can't really find it in SM. I just always want to give the very best to my 82 yr old Nanay. So it is the fondness and affection to us that counts. Not the cost of the box.
I think it depends upon the family you have, depends upon what you have and depends upon your innerside. Some people choose to be happy called as greedy, some people feels really happy to help. But most of filipino families are happy in helping each other. I have seen so many successful filipino families who did sharing and helping each other.
I believe, it is our culture having a close family ties.
I have also noticed that british people in general, understands and respects others culture. I watched t.v. and read their magazines and newspapers how they respect muslim culture, gypsys, indians and other countries.
So it is not difficult for me to explain to hubby and be proud of our culture.
