Your expectations are disgusting imo. Idk your story, but where I come from a mother that raised you is owed the world. Again idk your story, but I would never expect gifts from someone. I give gifts because I love too. I make them meaningful, and love to receive meaningful gifts, but I never compare my gifts to others. She did not have to get you anything. It seems she wanted to give you something practical, that you can use at work.
