The only thing I could add is how I handle PITA's and people who I think will be a PITA. I generally give a big enthusiastic smile and exclaim that my scoot has changed my life (it has) and that whatever activity I am doing would not have been possible before. I agree with KM, never apologize. Some people will still be a PITA but that really is their problem, not mine.
