TV - observations

I see that Kev has a new Bev. In fact both Kevs have new Bevs. GF finds this mildly disconcerting, and unrealistic. How could both Kevs find new Bevs, and within a year both be upgrading their cars. GF's worry is at several levels:

• What is the chance of both blokes finding new partners with the same name as the old ones?
• What is the chance of either of them still having disposable income after the split?
• Why do I care?
• Calm down - it's only and advert

Methinks GF is watching too much TV.
