Matters of fear that one is obligated towards his parents:[1]

The basic difference between the command of honor versus fear:[2] The basic difference between the command to honor one’s parents versus the command to fear one’s parents is that the command to honor one’s parents involves the performance of certain activities out of respect for one’s parents [i.e. Kum Vasei], while the command to fear one’s parents involves the abstaining from performing certain activities being that they are considered disrespectful to one’s parents [i.e. Sheiv Veal Taaseh].

The following matters are included within the command to fear one’s parents:

1. Not to stand in one’s parents designated area for standing.
2. Not to sit in one’s parents designated area for sitting.
3. One may not contradict their words
4. One may not arbitrate their words.
5. To establish in one’s heart a fear of one’s parents.[3]

[The above are only some of the examples of matters that one must beware due to his fear for his parents, and in truth there are many more matters that can be included.[4] The general rule is then any manner that can be viewed as disrespectful to a prestigious person, is prohibited to be done to one’s parents due to the obligation to fear one’s parents. Certainly, one may not say or do things that will get them angry.[5] One should not view himself as an equal to his parent, but rather like a servant before his master.[6]]
