Now that I've seen the face off at the mat--I think Margie was waaay over the top. I'm sure part of it was due to the stress and fatigue of the race.
But I think when she sees this on tv she will be embarrassed. I don't think she always acts this way.
It did smack of "Waahh! They're always picking on me/us" though.
And her insisting on giving Luke all those details over the period of today's installment smacks of trying to get his dander up over a perceived "insult."
I grew up with people whose major strategy in life was to look for insults so they could have a "poor me" response. It took me some time to see that there were many other more positive ways to approach people and life.
IMO Margie is not doing Luke--or herself any favors if this is her usual response to any perceived slight. It will take him a lot of work and much time to purge himself of that kind of "Poor me," they're picking on me" attitude and start enjoying life.
I've been there and had to do it. It can be done--but much easier never to have that drummed into you in the first place.
(Yes parents doing that to their kids is an issue for me. I only think about it these days when presented with such a clearcut example of it. Or if I find myself regressing to that old attitude in my own life.)
