I just saw an episode of 7th Heaven in which Melissa Gilbert guest starred. She played a single woman with a high pressure job who wanted to put her mother in a nursing home. The mother wanted to stay independent and felt her daughter was interfering too much in her life. The theme of the episode was mother/daughter relationships. There was another episode of 7th Heaven in which Kyle Richards guest starred. That episode also featured Orson Bean (Loren from Dr. Quinn). It's interesting how many times the same actors/actresses show up on different TV shows.
