Keeping my eyes on the piece, I grope my hands to the side to pick up the screw. It took a while to search the screw. But then the screw came in front of my eyes.
"Thanks." I said and took the screw from his hand.
After fixing the part. I handed him the screw and asked for a bigger size. He took it from my hand then displayed another one.
"Is this one?" He asked.
"No. That's too big. A little smaller than that. The medium one." I said.
"Ok." He said. And handed me the another one.
"Perfect." I said. Taking the screw, I fixed the other part. I then handed him back the screwdriver. There was one part missing in it. I searched my pockets to find the remaining piece. I stood up not finding the piece.
"Where is it?" I said, dusting my dress.
"What did you loss?" He asked.
"It was a small twisting screw, almost of half inch." I said.
