There’s a million things to watch out for, things to do and not to do to really get them off on the right foot, but it’s impossible to be specific about them without being able to see the two of you interacting, you need someone there with you to guide you. Most RI’s will happily do a half hour handling session with you to get you on the right track, and it doesn’t need to be often, but then you also have the added bonus that you already have a relationship with the RI when it comes time for backing or if you do end up with ‘the kevins’ as he settles in.
