I also think of specific instances of gifts. Again, I come from a Chinese community. Chinese New Year is about red packets. I get a lot of red packets.
Most of them are chocolates and so forth, but occasionally there's money in them. To refuse this, from my cultural perspective, is an insult, but then I actually take a look and see how much is actually in them. If I'm getting it from a family member, that's part of a normal cultural practice.
