Ali Hayati wasn't even born the last time Iran and the United States had diplomatic relations. But now, he feels like there's a chance for change.
"I want to see Mr. Rouhani and Mr. Obama sit in front of each other and speak about life," he said.
At the House of Persian Carpets in the famous Tehran Bazaar, merchant Sadegh Kiyaei said he's optimistic.
"We believe that two nations -- Iran and America -- they realize that they need each other. They like each other," he said. "And they feel that it's the right time to get together and to start talking at least."
