Plisss kak bantuin aku udah stress​

B. inggris i am so glad that today is
over. so many things have gone wrong. For some reasons I didn't sleep a
wink last night. i was very tired when mum called me this morning. i fell asleep againuntil mum called me again. that snooze made me late.

i did not have time for breakfast.
i was starving as I ran to catch the school bus. I just missed it. dad had to ride me to school. he was late for teaching at his school and he was furious with me. he scolded me for being late.

i arrived at school on time.
the teacher asked us to hand in our homework. my homework was not in my bag. i had forgotten to put it in my bag the night before. i usually check my bag in the morning. i did not do this because i was late i had to do extra assignment as a punishment.


After Biology lesson, I did not tie my shoelace properly. i tripped over it. and fell down the stairs. I hurt my knee and had have a bandage on it. What a terrible day! I hope that I have much better one tomorrow.

Questions:
1. what should the writer do to have A better day?
2. what is the main idea of the last paragraph​?​
