I just happened to be sitting outside of a cafe writing my friend Mary a letter when a bunch of college kids asked me to take their pictures . I fuddled with the buttons and the iphones and I gave 'em a little goodnatured guff . The one in the red baseball cap laughed the most at my goofy jokes and seemed pretty used to the fuss .

Question: Who ended up bothering the narrator ?
Answer: It was Mary .It was her friend .It was the high school kids .It was the undergrads .
