You ever read that Christmas story about the poor couple that sells things that are important to them to get something nice for the other?
Now imagine selling a random gift to get money to use on commodities like food, rent, or utilities.
We can't know what that person needed the money for. While overall I agree with the reaction of the poster, I can get off my high horse long enough to acknowledge we don't know the whole situation or the economic position of the family.
Maybe she would buy smokes, maybe she'd pay rent. We don't know.
As an anecdote from my childhood, we were poor. My parents often spent what little they had to get nice things for me and my sister. It came at a detriment to our home. We had much of what we wanted, but we lacked what we needed. As an adult now I would invest in the environment first.
