The past(possessive)...

I said sitting at my seat in our classroom.

Hannah: Why?

"You always get late and I've to ride fast to get to school on time every day due to which my normal speed became 70."

Hannah: That's good, you can ride fast.

"No, it's not. I woke you early but you always make an excuse to get late to school like you did today."

Hannah: Don't whine.

"I'll leave you behind if you get late tomorrow."

Hannah: Say something which everyone believes. What you said is not even possible in your dreams.

I facepalmed myself. She was right, I can't leave her behind. Our teacher came and the class began, the whole morning was good and it became bad at lunch.
