Bonjour voilà ce que j'ai fait j'espère que ça va t'aider :
Excuse me I'm late and I've got the wrong copybook:
-First of all my alarm clock didn't ring so I woke up late this morning
-Then I didn't do my school bag yesterday evening so I did it very quickly and I confused my English copybook with my French one
-And Finaly I missed the bus so I took the next one but it came 10 minutes late
-So this is why I'm late and I've the wrong copybook I'm so sorry about that.
