Should I say something stupid to a friend when she gives me a Christmas present
Why would you say something stupid to your friend?
I still think she's a stupid cow and it's not like I need this crap.
Then why are you accepting her a present at all? You should think things through before you give and receive gifts.
I want to shock her. It's crazy to give friends gifts like that. It's not always just the thought that counts.
Being so rude and unappreciative of her efforts will likely create tension during the gift exchange. Don't you want to enjoy the holidays? Saying thank you when accepting the gift will really add to the enjoyment.
