I think I will just be happy for the parents; enjoy our time in the new house; be mindful that negative energy doesn't arise; or if it does arise, be mindful that it doesn't go out of hand. I think that should be enough. It doesn't really have to be contrived.
In my opinion, the (formal) meditation practice is just a training for that sort of thing... it's not really a substitute, especially not in the everyday life. I think that's just me, though.
Hope the new place goes well for you and your parents.
