Adriаn wаs eаger fоr the schооl day to be over. He had arranged to meet some friends to play basketball, and he wanted to leave right away. The day crawled along, but finally the bell rang. Adrian jumped excitedly from his seat and loaded his backpack. He rushed to the door, but Mr. Benson’s voice stopped him. “Adrian, could you come here, please?” Adrian stopped and reluctantly turned around.

So he shuffled up to Mr. Benson’s desk. “You don’t want to forget this, do you?” Mr. Benson asked as he held out Adrian’s cap. In his hurry to leave, Adrian had dropped it on the floor by accident.“Thanks, Mr. Benson,” Adrian gratefully replied. Now he was glad he had stayed Which means the opposite of by accident?
