In the years before Twilight Sparkle came along (Pony Princess Twilight, not Crystal Prep Twilight) one thing confused her.

It happened around the same time every year, people would sell other people red paper flowers, and then a few days later on the Sunday gather in parks and just stand there in silence at 11 in the morning.

Who gets up to be somewhere at 11 am on a Sunday?
Why do they do it?
What are they doing for?
