What do you think about me giving my daughter's friend cupcakes?
What happened after you gave them to her?
She ate all of it and did not even says a word of thanks! That's the rudest person I have ever met
If you are expecting appreciation or other consideration because you gave a gift you should not be giving gifts. You are then attaching strings to the gift and expecting something in return.
That's true. I should not expect anything. I will never give any more presents to anyone.
Although it would be proper manners for someone to say thank you, you should not have expectations for others. Expecting gratitude will often lead you to disappointment.
