WTF #1

My number is 3. It’s just as simple as that and will never be altered.
Although I have favorite/lucky/preferred/ sub-numbers:
6, 9, 12, 15, 19, 21, 23, 25, 27, 30, 33, 36, 45, 54, 69.
And with 3 being my main priority, the lack of it in, say a big race, would be absolutely devastating.
This is my given tee for Human Race that also works as our running-tag (or whatever you call it) and we are requested to wear it.
I rest my case, your honor.
