The group gathered at Tyler’s to wish Donghua Xu well as he leaves us after 2.5 productive and fun-filled years. While we are excited to see him moving on to exciting new opportunities (including the chance to actually live with his wife), his departure leaves several as-yet unanswered questions. To whom will Taylor now teach idiomatic English? Who will state with conviction “you say this, but this is not right!” at group meeting? And what will Donghua do without questions of associative polymer physics to entertain him during his two weeks of vacation?
