I think that my problem with at least one family; the one that I have kept have "tagged" to be a legacy for me. I can't decide on Tamara or Derek, the twins I don't think I will have a problem with in moving out, set them up in a nice home and tell them to visit when they can. But Tamara, she is the first "child" that I have raised and I don't want to let her go, neither do I want Derek to leave, but I don't want to deal with two families.
I have become more attached to the sims than what I had expected to. I felt an irritation at Conner not just for cheating again, but for tellling his son on the day he aged up to teen. I know that is isn't real, but sheesh.
At least now I have a more postive outlook for my founder parents so I won't see them as a bother when they become elders, it will be hard to see them grow old, but that is part of life and I think I will just let them have whatever fun they want.
