Please stare at the image below for 10 seconds before reading further.
You are feeling calm, collected, and a little drowsy. You are feeling agreeable. In fact, you feel the need to do something nice for someone.
You have Guitar Ray, "You're Gonna Wreck My Life" on Shagg. You really liked this record when you bought it, and first listened to it. But frankly, you're getting a little tired of it. You think its current market price is too high. A more reasonable price would be, say, 400 pounds. The record doesn't matter that much to you anymore, and you'd like to share it with someone who would value it more.
In order to do you a favor, I am willing to buy this record from you for 400 pounds. (Are you sure you wouldn't feel even better if you sold it for 300?)
