♛My dear anonyme, this is not such a terrible crime.

You yourself are a gift to your father, and if he fails to see that, well, that’s his loss. Especially with how contrite you sound and how close you claim you are with him; the fact that he doesn’t take all that into account and allows you to feel like “the
worlds worst daughter” and “a total piece of shit” for such a minor transgression… not very fatherly behavior. Does such a person deserve a reward for that?
All of my fledglings, each in their own way, were gifts to me just by being themselves and my time with them was always far more valuable than any physical gift they could give. Seeing them blossom… being proud of them… knowing that they were made of the same material as myself, existing in this mystery with me, all that and more, those are the gifts that mean the most. …Even when they hate me, fight with me, and even try to kill me, seeing that ferocity in them still stirs in me a kind of thrill!
Don’t get this man a physical gift just because he’s thrown a tantrum over your not doing so. The concert should have been a gift from him of spending time together, not just his financial burden, which is how it seems he’s treating it.
Show him that you are the gift by doing something with him. Share a meal with him, play a card game with him, do some activity you both enjoy. If I was your father, that’s what I would have preferred anyway.
