When 11-year-old Tyler Sullivan goes back to school on Monday, he will have the ultimate excuse note for missing class one day last week - written and signed by United States President Barack Obama. Sullivan played truant on Friday to see Mr Obama in action during a visit to a Honeywell factory in Golden Valley, Minnesota. When the president finished his speech, the schoolboy took advantage of a chance to meet him. \'I was sitting in the front row,\' Sullivan told local television station KARE. \'I was pretty excited.\' \'I had a chance to shake his hand,\' the boy said, adding that the president asked him about missing class.
