Serving and honoring one’s parents with a positive attitude and a happy spirit:[1]

One is to serve his parents with a positive and happy attitude [i.e., Sever Panim Yafos]. One who serves and honors their parents with a negative attitude [i.e., Panim Zoafos] is [not considered to have fulfilled the mitzvah of honoring his parents at all[2] and is] punished for doing so [as serving them in such a manner causes pain to the parent[3]]. This applies even if he provides them with the best of foods [i.e., Petumos/Pisyonim], nonetheless if he does so with a negative attitude he is punished. However, in contrast to the above, if one shows a positive attitude and has good intentions, then he gets reward, even if the service itself appears negative, as explained next.[4] [Thus, the main thing is not the quality of the service, but the attitude and intent of the child. Based on this it is understood that the attitude one has while attending to his father and mother and the way he speaks to them is of the essence of the mitzvah of honoring them.]

Greeting one’s parents:[5] Upon the arrival of one’s parents, one should greet them with a smile and happy countenance make them feel welcome and at home.

Serving them with honor and dignity:[6] Based on the above, one must be careful to serve his parents in an honorable and dignified manner and everything that he does on their behalf  should be done in a way of respect.

Running to fulfill their wishes:[7] When a parent asks one to do something on their behalf it is a mitzvah to perform the deed with alacrity.
