This morning's episode of Bharathathil Dharmam was another thought provoking one.
Mathrudevo Bhava, Pithrudevo Bhava
One must take care of one’s parents irrespective of whatever complaints one has about them. Even if the parents are at fault, it is one's duty to be in touch with them regularly (in case they are not staying with you). Do not interfere with their day-to-day activities but ensure you are there for their support whenever necessary. This is applicable not only to one's parents, but also parents-in-law.
For "Aacharyadevo Bhava" Sri Krishnan gave a very cute example
We have to offer what we like to God, but what we offer to the Guru has to be what the Guru likes. You have to ensure that you do not give the Guru something that he does not like.
