I don't want to go to a saint patrick day festival I invited my dad to
Why don't you want to go to the festival?
I tend to have trust issues with my dad.
You shouldn't cancel plans at the last minute. You should talk to your dad about these trust issues instead of running away from them.
What's the point in risking it. I can just not talk to him about it and go anyways.
It is good that you are not canceling on him on the last minute but you can still talk to him about not wanting to go. It will probably not make him happy to know it is going to make you unhappy.
