Wow loaded question,

its different for everyone, I've read that for the WAS, for some anyways its even before BD date. The date is something the LBS uses, its been over for much longer than that for the WAS, but it all just depends on the people involved, the way they were raised, the situation, kids, work, etc etc.

I think I've read a few places that 2 years is pretty typical in a lot of situations, unless your talking MLC, in which they might NOT ever come out of it. But again, there are so many variables to consider that its best to not put a time frame on it either way. It takes what it takes.
