+- a friend of mine asked if it makes sense to define your own wrapper class for `SDL_Window` the way [Lazy Foo](https://lazyfoo.net/tutorials/SDL/10_color_keying/index.php) does it.
+I told him there's no reason to do that in modern C++, because `std::unique_ptr` can do everything for you anyways.
+
+### freeing C memory automatically using `std::unique_ptr` and `std::shared_ptr`
+
+<sub>on another note, I did read a blog post about this once somewhere, but couldn't be bothered to find it. so there you go! I made a post about this too.</sub>
