Pink

I had a friend who lived in Jasper, Alabama. She was crazy about the color pink. Pink this, pink that, pink everywhere. At Xmas, she had a special, small tree - in addition to her other two Xmas trees - that was entirely decorated in pink. And not only did she admit to it, she bragged about it.

I have rarely rested my eyes upon a pink Xmas tree, but we ran into this specimen at a Waffle House in Conway, Arkansas:

I have no doubt that you'll agree it's an exquisitely beautiful pink Xmas tree. However, they, too, had an alternate, traditional tree on display.

Which prompts me to ask -

Is this pink tree phenomenon a Southern thing??

Does a pink tree always have to be accompanied by a traditionally decorated tree?

And,

why??
