Can anyone tell me how to handle Flat Stanley's Visit when I don't travel at all?

My dear cousin decided to elect me as the one who Flat Stanley will visit and travel with (for her son’s 3rd grade class.) But I don’t travel anywhere and have only been to a wedding since I was elected. I feel bad for my cousin’s son since he says all the other students have received so many correspond item from their F.S. and he has had only one. ( I pretended to take Stanley to the wedding…) I have a full schedule of my own but feel very guilty about not handling this subject. I should have never been elected without being asked first but now that it’s a done deal I have to find the easiest way to get as many Flat Stanley corresponds sent so he doesn’t feel left out. whew…. help.
