"Never mind, I have another one."
After a while, the paper was handed out and we began to do it. However, halfway through my thesis, I suddenly heard someone whispering. I listened carefully. It turned out that just now, my deskmate borrowed a ruler from me, but I didn't have it myself.
My eyes are moist, and everything that is clear is blurred. How pure this friendship is! There is a deep warmth in my heart.
