You had decided to go buy a Christmas tree, so you could decorate it to your liking these holidays. And that's why you had brought Hobie with you, so he could help you find the best tree. (Although he won't like that kind of thing.)

"I really don't understand the need to buy a Christmas tree."

Obviously, Hobie was going to give his humble opinion regarding the prices of these plastic trees.

"All this is an invention of capitalism to steal from people, nor is it that trees last so important... Worst? The thing is that companies become millionaires thanks to the money they steal from the people who bought these useless trees, which on top of that are made of plastic and pollute."
