Hello y not,
I missed the spouse! I may get into trouble with my wife.
It should be parents, spouse, children, siblings, extended family and friends, etc.
Of course, this is not a set order. This is actually what I believe the order is for me. For another person, a close friend may come much closer, for example.
So, don’t take this order too seriously. Parents definitely come first, because they are the ones who gave us a chance to be born with a human body. There are billions of human gandhabbas waiting for a suitable womb. Killing a parent is an anantariya kamma and killing any other (except for an Arahant) is not. Of course, killing an Arahant comes under a different category based on Arahant‘s moral standing.
