True & Honest Fan
It bears mentioning that Jamie wasn't a rando.I think I've never read the sentence "He admitted" as many time in those two years than in my whole life.
Yet we are still waiting for evidences of such things, and don't even think about pulling the good ol' "He yanked on her hair". Vic said himself that it was a playful tug because he noticed she had a new cut, do you know that between women we all did that at least once when we got new cuts and hairstyle ?
If it was Jane from the corner cubicle and Vic pulled her hair (I'll throw them a bone and assume the worst possible interpretation of the interaction). That might be kind of weird.
The dynamic changes entirely when you remember that it was Jamie who initiated the hug and was showing off her new 'do.
If a (seemingly) good friend is excitedly showing you her hair, sure, it might get a yoink.
