Answer: Yes, Gloria and Michael have friends, but when they got married they decided it was best to live *rent free* with Edith and Archie, while Mike was going to college. Living with friends rent free, for quite a few years, is not an easy thing no matter how close the friends are with them. Since the Stivics needed their money to pay for the tuition and its other costs, their living arrangement made it all easier to deal with. Hence the Archie and Mike scenarios.
