I would never say, "Slam the door and lock it," although I would certainly understand that choice. However, I sure don't think this is a time for "all is forgiven, open arms," either. What she needs to fix, she needs to fix it on her own two feet, by herself, on her own. Again, IMHO.
Yep. Or, as I like to say: "This is your mess -- you need to clean it up."
