Call me mean but I'm not going to let my dad eat one of my homemade cupcakes.
Why don't you want him eating them?
I really don't like my dad so I'll suggest he buys one in store.
Regardless of your feelings for your dad, I think you should share the cupcakes.  It's rude to not share things with your family regardless of the situation.
I want to be rude to my dad. I do not like my dad and I want him to realize this.
You should share with him. This will only make your relationship worse.
