I disagree from this standpoint. Sarah clearly thought about giving up, but she gathered herself, thought the situation through (focused on her knee instead of her feet) and mustered the courage to keep going. She admitted her weakness, overcame the temptation to quit, and was able to enjoy it when Todd climbed the same mountain with no problem.
Thinking about those personality traits in a president (unlike the current limp-wristed pansy who looks for compliments and awards when he has done NOTHING) tells me a LOT about Sarah's character. Just my take...
B-b-but, sh-she IS a QUITTER!!!!!! She really, really is a quitter! And you know that, don't you, smartypants????
LOL
