Three Twos and Ones(12-21-21)

One two three of them
Two in the same sequence
One not alone
But twos and ones
They are twos and ones seen

What could this mean

Is it a message for me to catch or in mental state universal stored in cache

Let out when ready
But I'm thinking as it closes in on the holiday
Is it for then or is it for today
Hmmm as I go throughout the day
