I don't do gift giving holidays
That's not usual. Do still go to the gift giving events?
Yes, I receive the gifts but I do not give any out.
If you go to the events then you should participate in gift giving. It is not fair to the others not to reciprocate with gifts of your own.
I already told you that I do not give gifts out.
Holiday events are a time of giving and receiving and you not participating in both parts of the event is not good. Other people will feel left out and used by you if you don't bring presents for them.
