From time to time I will take money from children who don't have any.
WHy would you choose to take money from needy kids?
Because I like to think about the fun they'll never have
You should not take money from needy children. It is selfish and cruel. You should consider others instead of yourself, and reflect on what you can do to help needy children instead of taking from them.
I know, but I can't help myself and money isn't that important anyway.
You may not believe money is important, but for them it could be the difference between life or death. You should not take things from children, especially not poor ones.
