Brussels' biennial flower carpet. This is when the city of Brussels takes what is, in my opinion, the prettiest square in all of Europe and dolls it up with a couple million begonias.
Every two years, there is a different design. In 2014, the theme had been a celebration of the Turkish rug. With its jewel tones and symmetrical pattern, the flower carpet was glorious. The hotel I'd stayed in was both funky and fresh. The weather had been (mostly) good. Overall, it had been a great trip which I remembered fondly and mentioned every time someone brought up Brussels in conversation.
That is exactly what I did when a coworker told me she was thinking of going to Belgium. Realizing that it was an even numbered year, I pulled out my phone to check for her when the carpet would be displayed. It was that very weekend! She was off the weekend after- too late for a carpet that is only on around for four days -but in a twist worthy of one of the crappier M Night Shyamalan films, I did have the next couple of days off.
