Marcus went into a shoe store on Fifth Avenue. He asked if they sold Timberland shoes. The salesman said yes. Marcus walked to the back of the store with the salesman. A pair of Timberland slip-ons were on sale. They were size 11-1/2. Marcus asked if they had size 11. The salesman said no. Marcus tried on the slip-ons. The left one fit okay. The right one was a little loose. I just need thicker socks, Marcus thought. He decided to buy the shoes. He wore them the next day. By the end of the day, he was limping. He had a red sore on the back of his right heel. The red sore didn't heal for a week. Marcus wore flip-flops all that week. "How could you buy shoes that were too big?" his wife asked. He said, "Only one shoe was too big. Besides, they were half price."
