Why do some people only care about gifts when they're receiving them, but not when it's their turn to give one?

I'm on the sister's side here. We're ALL on the sister's side. I would be hurt if my brother didn't even get me a birthday card and then even dare to expect me to shop from his Christmas wish list. Oh, I see his objections to presents come with seasonal exceptions. That must be convenient, right?

And no, having a birthday doesn't entitle me to an expensive present. But it is a day when people you love make something special for you. I wouldn't calculate what somebody "owes" me based on their salary. That 5K a month mentioned in the story does nothing but reinforce that what stands out here is the lack of effort. A few handwritten lines would have shown that he'd at least thought about her. But he wasn't even capable of doing that.
