Would you be upset if a friend doesn't reciprocate a birthday gift?

I know that you shouldn't give with the expectation to receive. But would it bother you if a friend doesn't get you anything for your birthday when you got them a nice gift for theirs? I bought my friend a necklace for her birthday, and she just sent me "happy birthday" (not even a longer text) for mine.
