I would add a crowd draws a crowd. If you walk down the high street and see a crowd all gathered around something you cant quite see, you join the crowd as does everyone else to see what everyone else is looking at.
Then crowd mentality takes over and everyone follows suit. It’s the same if you stand in the middle of a shopping mall and look up, everyone walking past will look up too, to see what they are missing out on!

Great post, re-tweeting it now

In Norway, where I live, few people have the displays on their houses. Once in a while you’ll spot them, but there are no streets like yours.

I agree with all your list, especially about the good planning part.

I think it’s important to learn about time management as well. It’s hard to get everything done if you have little time. And I guess most of the people with the christmas light displays have a family. If they do, they need to plan and focus on what’s important, and leave the unimportant stuff out. Because it’s impossible to get everything done.
