Well, your father will be very happy if you tell him how much you enjoy the 枇杷. As a parant, just want to watch how the kids enjoy eating, playing ...
So, if you say you don't need anything, end up their have to guess and buy what you need, and end up you don't like it, is the worst thing. Don't feel guilty, but just show them how much you enjoy their love.
I think you will find out all this kind of feeling in few months.
Couldn't wait to hear your good news.
