You realize after the fact, your family cannot travel certain places for free because you have this companion and had you not listed them, your family would get better benefits. Your family is planning a trip to Europe and now they have to pay a lot.
Do you mention this to your friend? Your father could be going to Europe for free had you not added this friend, now he has to pay. Do you ask for any reimbursement? Not a lot, just $50-100. Do you leave it alone and say "now I'll know next time"?
I just feel bad for my family... but I didn't know.
