I had my orientation and I never told my dad about it.
Is there a reason you haven't told your father?
I didn't have a chance to settle down and speak with him about it.
There is nothing wrong with keeping things to yourself. Not everything about you needs to be said to other people. You can tell your father when you are ready to.
I won't be able to before Friday, when I visit him.
You shouldn't feel pressured to tell your dad about your orientation as you can keep things to yourself if you choose. Either way, do what feels right for you and know you have nothing to feel guilty about.
