Darn! I so hoped Chris and Mindy had dumped these moochers!
It seems as though, given this last trip they took, Chris & Mindy have tried to create some distance without any actual controversy? While they are very different in their capabilities I believe Mindy & Dawn are both a bit introverted & submissive & there is a bond there between them. Chris does not appear to have a controversial bone in his body & will avoid it at all costs. And there are many people who will quietly submit to the bad behavior of others simply because they fear any kind of confrontation or rejection, & thus they continue to subject themselves to it & let others portray them as the victim. Chris & Mindy fully understand that Will takes advantage of them in any way he can. They simply choose to accept it to avoid what they fear & out of pity & consideration for Dawn, & Mindy’s bond with her. So they leave a day before they know Will is to return knowing he will attach himself to another one of their trips & travel on their dime; no controversy! They certainly seem to be very nice folks but they are weak in that way, vulnerable & Will knows it! I used to tell coworkers, if you choose to be a doormat then shut up & get used to the taste of mud in your mouth! Until Chris gets a mouthful of mud too big to swallow they will just keep trying to find those sneaky, non confrontational ways to avoid them whenever they can, without anything confrontational of course!
