A guitarist was pleasantly surprised to hear from New York City police that his valuable guitar had been found. It disappeared almost a year ago when he got out of a taxi and forgot to take the guitar with him. Laurence Lennon, 44, said he was running late that day. He was talking to his manager on his cellphone when he rushed out of the taxi. He said that he gave the driver $60 and told him to keep the change. He walked through the front doors of the concert hall, still talking on the phone to his manager.

Upon discovering his loss, Lennon used his cellphone to call the police. The policewoman asked him for the name of the taxi company, the number of the taxi, and the name of the driver. He said that she must have been joking.

She told Lennon that he could apply for a missing item report online. Lennon asked for address. It was www.nypd.gov/toprotectandtoserve/haveaniceday. She told him that finding the guitar might take a couple of years for finding guitars was not as important as finding murderers and marijuana (大麻)smokers. Then she told him to have a nice day.

“This year has been depressing,” said Lennon.  “I had to put off the recording of two new CDs. I’ve been using borrowed guitars. And I was losing hope of ever recovering my guitar.”

Lennon was reunited with his $100,000 guitar yesterday. The guitar had been discovered in the corner of a coffeehouse only two blocks from where Lennon had lost it. Lennon had offered a $10,000 reward for its return. He said he would give the reward to the coffeehouse owner, who had informed the police.
