I'm expecting a better gift
Why do you think you should get a better gift?
I deserve to get what I want.
You need to be more realistic. You can't expect everything to be perfect all the time especially with gifts.
I don't think it's unrealistic to expect the best for me.
If you have too high of expectations you will only feel disappointed. If you have a real issue with this I think talking to a therapist might help you set realistic goals.
