TG's words are wise. Life is precious, time is finite. We have our kids.
And if it helps at all... you can see that the going on trips/holidays that the WASs do is part of the script.
It helped me to look at it like this. If they do this, it's one more box ticked; one more 'attempt' by them to find what they are looking for. And hence, they are one step closer to coming out the other side of this mlc process. It's like they HAVE to do these things.
Now, no guarantees, I know, that they'll gain some insight, but if you look at it as a necessary part of the 'learning/changing' process for them, it might help you to endure this.
