thanks.
I know that he wants what's best for me. I just felt a bit frustrated. JZK.
It makes perfect sense that you should feel frustrated. Perhaps you feel that he has granted himself a freedom that he has denied you. But as others have intimated, this really isn't about your father's level of submission, but yours.
Let's remove the religious undertones and look at it a slighty different way. One of these days you are likely to have children and will want to raise them in a way that insures their safety. For that reason you will probably teach them specific rules about crossing the street: look both ways, hold your hand, and always be sure to cross at the crosswalk never in the middle of the block. Well, I can pretty much guarantee you that one day they will witness you crossing somewhere other than a crosswalk. Does this mean that they should ignore your instructions? Certainly not. For the time being you are the one who gets to make the rules for them, and it matters not how or why you choose to do differently for yourself. There may be perfectly legitimate reasons for you doing something different than what you have instructed them to do, but how can you explain all of these things to them when they are young? So, while one day they shall be able to make these decisions for themselves, for the time being, it is important that they listen to your instructions regardless of what they see you doing.
Your father's decisions may not make sense to you know. And though you are not a young child, still you are under your father's authority. Accept that, respect that, and live by it gladly and you will find your frustrations level decreasing with your increased willingness to accept his guidance in these matters. There will come a day when you can make this decision for yourself. And the time is probably fast approaching and you feel (maybe even are truly) ready for it now. Viewed that way your frustration may not be so much about this single decision of your father, but simply the very natural frustration that comes when a child is ready to become more of an adult and independent than her parents are ready for. It is a time in life we all pass through. But have patience; one day it will be behind you, and much sooner than you now think.
In the meantime think of it not so much as being frustrated by his decisions, but an opportunity to show your father how much you love him by showing him your respect his decision on this matter.
