I write things quite a lot, usually a list of things I need to do or buy, or sometimes a story, and I write my school work.
Sometimes I like to write by hand and sometimes by computer. When I'm writing a lot I like to write on the computer but if its not that much then by hand.
I don't know about this question.
One day, but I hope they don't.
I think I learned to write at about 4 or 5 (I'm from England.)
To fill out forms where necessary or add my signature to things. Otherwise I don't really write that often, which is a good thing because I have an awful handwriting that has just gotten worse from the lack of use.
