Oh, so you're the one who started the abuse of Shakespeare. Keep it up, and you'll go blind. And take another look at your sentence -- do you insist on shanghaiing Shakespeare on your linguistic misadventures, or are you willing to take responsibility for your own poor English?
"ungrateful adj. without gratitude."
"gratitude n. a feeling of appreciation for a kindness or favor received."
New Webster's Dictionary and Thesaurus of the English Language (Danbury, CT: Lexicon, 1992).
In the absence of a prior kindness or favor, one cannot honestly call anyone "ungrateful."
It's blantantly obvious, the more your post, that your father hasn't given you enough ( anything ? ) and that is the cause of your bitterness. It doesn't speak particularly well of you, that you feel so free to condemn him, repeatedly here. That's ingratitude, dear. I suppose that now you're going to tell me that you don't owe him any. Has he been that bad a father, or just not forthcoming enough to suit you ?
