Regardless of all the polically correct and selfless answers you are getting. Providing a gift shows that you respect and appreciate what was done for you it also shows you have some class
Accepting a gift graciously shows class, AND it makes the giving experience for the giver more fullfilling when they see that it is appreciated.
A gift is just that...a gift. You should accept it in the nature it is given.
Like salvation!
