Just like any time you check in with a friend you haven't seen in a very long time, interactions can be awkward at first. Unmet expectations and feelings of loss are a definite possibility. These characters have been suspended in reruns for almost a decade and all of a sudden, they've arrived in our present. They're using smartphones for god sakes! If they don't act how we expect them to, our intimate relationship with them and the show is at risk. I have no doubt it will all take some getting used to.
