Yesterday was Good Friday. I always wonder, what's good about it?

I chose a flowering dogwood to commemorate the day, because it is said that the 4 reddish marks on the tips of the flowers represent Christ's blood on his hands and feet. Kind of morbid, but the Granny Smith apple-green color of these flowers are so refreshingly pretty, it hardly matters. Complementing them are tiny daffodils, giant tulips and ruskus leaves. The tulips are so huge, I wonder if they used steroids? I opened up two of the tulips manually, just for fun. They look like completely different flowers, don't they? Do you like tulips closed or open?
