biology

*cringgg* *cringgg*

The alarm clock woke me up,as what i always do,i brush my teeth,washed my face,take a bath,eat breakfast.
Bring the 2 canned fresh air o bought yesterday at the students lounge vending machine.
I remember that at the end of my street is the train station,i go inside the train,go to the empty seat.

"Hello"

I was shocked by the voice i heard and realized its audrey as she greeted me.

"W-well h-hello, didnt see ya there"

" can i seat next to you?"

"Well yeah,go in"

As she's about to sit next to me the train starts to move.
The train was not full of passenger and it looks like just both of us.

Were almost at the last station where my school is...

When whe arrive at the next station
Audrey said she's at the same school with me.

"What room are you?"

"Room 03,how'bout you?"

"Really?!,im room 3 too!"

"Well why i didnt see ya yesterday?"

"Well because i skipped the class yesterday"

As we enter the room 3 door
The class is noisy and our biology teacher isnt here either.

*creech* the door open

"Mornin' class,ey sorry awas late eh"
"Todays lesson is about trees anyone heard of it,knows it?"

"Tree?" The confused student yesterday asked.

"Never heard of it".a student reply

"Well tree is a plant or a living thing that give us oxygen and fresh air"

"Well why things go bad when you dont use your air freshener outside the school building? A student asked again

"Well because its extinct"

"Why? What happened" asked the confused girl.

"Because trees was cutted down by almost everyone".

"If trees never go extinct we really dont need to use that air freshener"

Thats why our surroundings is preety plane

"Do we really need tree?" One student asked

"Yes thats why when youre outside you cant breathe because theres no oxygen like theres no tree.

So there is this thing that give us oxygen?
Then if theres no oxygen why we cant we breathe outside,but can breathe inside of a building?.
