I'm so tired I have to stop going to bed at 4-5 Last night I read my book until 5.30 because I really wanted to finish it

I can predict my day now...I will do my science coursework and hopefully finish it, if I do I will start on my other science coursework. I will then text my friend telling her I can't come to the sleepover tonight because I have a family do, when really I mean that I don't want to come beacuse the friends that are going (and her) have developed a tendency over the past..few months to smoke weed and she's already said to me on the phone that they are going to hang out the window and smoke it and I really don't want to spend my time doing that...I don't mind drinking but. I draw the line there (she also told me she spent £40 on weed..)

I will spend my evening doing coursework, watching the telly and stopping the cat from going outside (I like this version of the evening much better)
