Yesterday was an absolutely terrible day! Everything that could have gone wrong actually went wrong.

It all started in the morning. I didn't hear my alarm clock, and as a result, l overslept. When I finally got up, I looked at the clock and understood that I wouldn't have enough time to have breakfast. While I __ __(was running/ran/was being run/have running) downstairs to the

kitchen, l accidentally fell over. That was painful! When l entered the kitchen I saw that breakfast __ __(was cooking/was being cooked/cooks/cooked)

mother. It __ __(smell/was smelling/smelt/was smelt) so tasty, but l

couldn't wait for it to be finished. So, I

grabbed an apple from the table and rushed to school.

At the first lesson, I suddenly realised that my homework project __ __(didn't finish/hadn't been finished/hadn't finished/wasn't finishing)

When the teacher asked everyone to hand their projects in, I had to apologise and

give my unfinished homework. The results are not readyyet, but I think my project will be marked as unsatisfactory.

After school, I went to the hairdresser's to__ __(dye my hair/had my hair dyed/having my hair dyed/have my hair dyed) . When the work was

completed and I looked in the mirror, I went numb. My hair was not the colour l wanted! I asked for the blonde one, but instead, it was almost red! However, I calmed down

and decided to try to

__ __(get used/use/used/got used) to it. In the evening, I had to go to the service centre, because my laptop wasn't working. I needed to __ __(had it fixed/having it fixed/fix it/have it fixed) as soon as possible, so l sat there and waited for about two hours.

Finally, I returned home at 9 pm. I was

exhausted and disappointed. My parents listened to the story about my day and suggested that I go to bed early and simply relax. That's what I did.

Todayl feel a lot better! The day has started well enough. It's only 7 am in the morning now, but I'm looking forward to the things the new day has for me. Anyway, it can't be worse than yesterday!
