Do nursing homes call back saying they would love to care for your elderly loved on again?

Before my mother went into the nursing home she is in now, she was in another one for a few weeks before she fell and broke her hip. Since April, we will get a phone call from that nursing home asking how my mother is doing and saying if I ever need them to take care of her, they would be glad to have her back. To me this is blatant salesmanship and today they called again. I let them know to please stop calling.
