We used to call Air Bear Tesoro, and other terms of endearment. But one day when Air Bear was almost two, his Mother called him that, and he said firmly, Don't call me Tesoro, My name is Mr. B. And what does B stand for? we asked. He responded—a little annoyed that we didn't get it—B is for Air Bear. Since then, Air Bear has been speaking up for what he wants and believes, even if it's a little unconventional. B does stand for Air Bear.
