Near as I can figure out the timeline, Kirsten had graduated college or was about to when she met Sandy. She has an art history degree, according to the Girlfriend. And before they moved to Newport Beach when Seth was six, the Cohens were living in some house in Berkeley. (Where Sandy was a public defender, even then, because he's been a public defender for 15 years when he leaves it for the big firm.)

I really need to find some way to get this canon whoring to pay. In fic, at the very least. (Yes, Maggie, I am looking at YOU!)
