I have nothing against buying things, and getting a good deal when you do. But, to make up a pseudo-holiday strictly for that purpose seems a bit manipulative.
And that name- "Black Friday"! Always sounds like doom. Who would want to be a part of that?
I have never participated. Partly because I don't wish to be trampled and mauled. Partly because I've never had enough money to spend to make it worth the effort.
However you spend the day, I hope you enjoy it.
