Have I been wrong?

When you think everything is going right, actually a lot is going wrong. Three is a bad luck number for sure. Three friends never work out. One will always be left. So is there with school, friends and sleep. If you combine sleep and friends, you have no education. If you combine school and friends, you have no sleep, but if you have sleep and school. You have no friends. I belong in the third group. See? Three again. When my homework goes well and I sleep enough, my best friend leaves me, but can I call her a best friend if she does this to me? After all ive done fo her. Is it me then or is it her fault? Or is it no ones fault? A lot of questions, with no answers...
