A complicated question?

Why is life so complicated? Why is life so dreadful? Why am I asking such questions? Why can't I go to boarding school? Why can't I enjoy life with out interruptions! Why can't I destroy this computer? Why can't anyone..................................… I wish I had a tree house! I'd draw peacefully up there and paint! Speaking of paint about how much would a canvas cost? And if you paint on it and made an error can you clean it off or will you have to use another canvas?
