I agree that the card is very important, but I wonder if it is only important to 4's? I can just hear Mojo chiming in with, "He11, I don't care about the card, what I want for my anniversary is a good fcuk!" I mean 4's want that, too, but only if it is accompanied by a great card! NOT.
For my birthday last year, my bf got me a "friend" card. It had a long poem on it and he thought (or pretended he thought) it was the perfect card for me. The word "love" did not appear at all. It was the kind of card you would give a same sex friend or possibly even a work colleague.
However, he made up for it on Valentine's Day where he gave me the best v-card I have EVER gotten from anyone. I struck just the right note of how our R was/is life-changing to him without going into the "you are my everything" zone. It was perfect.
