I don’t think that accepting the present from your parents is selfish. They want to present a gift to you personally for your efforts in studies. You buy yourself things, clothes, without any regards to what you could spend this money on charity. A tablet is not only a toy, but also a useful thing for study, it will definitely come in handy at the university. When you graduate from university and start earning your own money, you can donate much more to charity. I think everyone has the right to make his own decision.
