If someone will give you a christmas gift, will you do the same for him?

I believe that giving gifts is not an obligation to do specially if you're given first. Because if it is the case, it will be called an exchange gift. Personally I love giving gifts to people who can't afford to give me one. Those people who don't ask and don't expect anything from me because I know it will be much appreciated than the one who have been expecting and asking from me. Giving gifts should come from the heart and not just because you are force to do it. But if you feel that you really love giving a gift in return then that will be great.

Of course. In fact I always want that I am the one to give first.

Well for me if I am really his friend and given me a gift, why not just to show that I also appreciate him I'll give him a gift also. Anyway it's something I can afford to give. Anyway Christmas is only once a year! Advance Merry Christmas to you and your family too!

I would feel an obligation to get someone a gift if they got one for me. He might expect you to buy something for him.

It does seem like you're obligated to buy your friend a gift after he tells you that he'll buy you one. You could buy him a giftcard, or regift one of the gifts you'll receive. That will seem cheap though so you might want to just give him a thank you card and maybe eat out to lunch or something and pay. Something nice like that is always great things to do for friends.

not necessarily. because i think that if you decide to give something to a person it should be coming from the heart and it's your own will to give. you must not expect something in return if you give gifts to someone.

Its not an obligation...giving gifts should always come from the heart. Cause its always the thought that counts.

Of course, you should give back one to he or she to be nice or polite. That's maybe what most of us do to our friends. Somehow, it maybe a little troublesome to do this, but I think I should do that if it comes to me. You may make this task easier by make the present yourself. Though it may not that nice as those sold in store, but it will be more meaningful.

it's not an obligation but an initiative. as you said the gift is unexpected so the person who gave this gift is not really expecting something in return. you should not feel guilty about it.
