His "point" was a meaningless platitude. "Everything will just work out, it did for me" is not a point. Marten dismissing her legit concerns by pointing out he fell backwards into a job he had no qualifications for is not helpful. He means well, but everything Claire said was true.
Yeah, going with a 'nope' on that one. Life can be a completely random shot in the dark sometimes. Marten didn't seem to be trying to dismiss anything entirely, just mitigate it. Claire's kind of doing a classic 'glass is half empty' view here, and the honest counter to that is glass is half full. 'Yes, bad things can happen, and you can have things not go to plan... But then good things can always happen even if it's just from being in the right place at the right time.'
Also, call me just a bit crazy, but I'm just not fond of her attitude. I agree with some of the other comments to the tune of her never having heard 'no' about things growing up. *sigh* This will be misconstrued as an attack, which it isn't, but legitimately in my experience many of the people I know, at least around here, who have done the transformative thing, have some symptoms like this, attitude-wise. I could be entirely wrong, maybe it's a defensive reaction to all the negatives in their lives. (you know, along the lines of 'I'll be damned if I'll be told who and what I can't be'), or something like that. Or it could just be a Claire thing.
Either which way, wasn't a huge fan of her essentially crapping on Marten for being (occasionally clueless) Marten last couple episodes, and to now crap on his attempts to make her feel better as well? Eh.
Pretty clear to me she just doesn't WANT to feel better. When someone tries to lighten your mood and help you not be overwhelmed, the appropriate response is NOT slapping the hand they reached out to you. Least where I grew up anyway.
Last thing I want to point out is the 'again, this isn't an attack...'. I've run into this a couple of times. If you have to point out TWICE that something isn't an attack, then you probably ought to rethink what you're about to say. Case in point, I did ONCE above, and STILL put some extra thought into it. As my ex-wife used to say, 'Saying "Don't take this the wrong way", doesn't give you unlimited license to be an ass.'.
'I need you to understand where I'm coming from', after all this basically my read would be she's coming from a place where she hasn't, doesn't, and isn't interested in considering anything except the (tm) 'One True Path' that she's divined for herself, and if/when it probably fails massively, given both the current ratio of jobs/collegiates in america and the history of the comic's characters, she's pretty much out of luck without EXACTLY the same kind of dumb luck of Marten's she's been dumping on a bit here. Adaptation is key, and I'll be surprised to see her do that moving forward.
God, I'm getting old and it shows.
