What are you, nuts? Have you ever stepped on a holly leaf? You start putting that stuff in your hallway, and after one barefoot adventure, you'll be thinkin' twice about all that falala-ing. You'll definitely be singing a different tune. So let's keep the holly outside, and in the ground where it belongs.
The trees at The Living Christmas company may not be in the ground, but they do live in pots with dirt so they stay alive. Living trees are happy trees, and happy trees smell better, and last way longer. So, aside from D being for "Decking the Halls", the only other thing I can think of is:
D is for Delivery.
One of the coolest things about The Living Christmas Company is that instead of you trying to tie some tree onto the roof of your car and driving through town thinking the entire time "Please, please, don't fall off!" our elves can bring the tree to you. How cool is that? Then, after Christmas, instead of dragging it out to the curb, leaving a huge trail of needles behind, our elves will come and pick it up again. Now we can't guarantee there won't be any stray needles, at least it will be carried off as carefully and safely as possible.
We can deliver the trees, you provide the love that will surround it. It's not about the gifts, it's about the "presence".
