To amplify - by the time most Americans die of old age, they've usually moved out of the house they raised their family in and lived most of their adult lives in. Maybe they move to a smaller place, maybe they go into the Old Folks Home. Not my parents. They bought that place in 1962 and lived there till they died at 89 (Mom) and 100 1/2 (Dad). And now my sister, who made sure they could stay their through he end of their lives, owns the house (that was the deal), and plans to retire there herself. So it feels appropriate to us for them to be there. And it's not like people don't keep the ashes of their loved ones around.
Maybe not so weird. Or at least, not abnormal.
