Someone who is kind, generous and funny, but who is incapable of staying quiet for long enough to compete in a sponsored silence in the work place even if to raise money for a good cause.
After the claxon went to signify the commencement of the sponsored silence Diane caved in and let out a very loud guffaw, thus rendering her attempt null and void. Good effort though Diane. At least you made it to the start line.
