Old speakers returned

Another friend want me to return audio speaker set that he gave me few years ago, they had been obtained with his first paid salary and memorial device are the reason, so I accepted his proposal without any argument. To tell the truth, the device had been broken and internal network parts were replaced into new high specification semiconductors and capacitors, now they have far better performance than original designing condition. But, considering about his sentiment and he is only a amateur in the field, I'll return them without saying a sarcasm but with pleasure. I'll never accept them again if he wants to move them back to me because of relatively large keeping space.
