*wraps my arm around your shoulder*
There's nothing stupid about Milf action, my young friend. Heck you're 16 though, you gotta put yourself in some of us old timer's shoes. Some of us have been playing these characters for a decade, some literally since before you were born. Of course they're attached and of course they're upset. But the way I look at it time marches on. Yesterday's supple young babe is today's milf (I'm looking at you, Cass) and as you get older you'll come to see that what you once thought was ancient doesn't look so bad. You'll have plenty of time for it to happen to you though. And when it does I'll be there, not quite dancing on account of my bad knees and replacement hip, whipper snapper.
By the same token I can live with change. But I want muh milfs!
