It is important to remember that if one doesn't keep a Halacha that he should be keeping in order to honor one's parents then it is an Aveirah and Hashem takes Aveiros very seriously.
If one offends one's parents where it is unnecessary then it is ALSO an Aveirah and Hashem takes Aveiros very seriously.
So it is critical to receive guidance as to how to navigate between careful observance of Halacha together with sensitivity and care towards one's parents.
