Yes! Of course I know how to make spaghetti. It's very easy. All you do is fill a large pot with water and add some salt. Put the pot on the stove.
When the water boils, put in the spaghetti and let it cook till it's soft. But don't cook it too much or it will be too soft. Then take it off the stove and drain the water. And that's it -- the spaghetti is ready.
The sauce? That's a bit harder. I think I should write that down for you.
