Symmetry?

So I signed up to do A Year With My Camera and a 12 Days of Christmas photo challenge was in the welcoming email.  So I got one image with the rule of thirds.  Next is two photos showing symmetry.  At  lunch today, I set my candle holding reindeer that I put alstroemeria in for the Christmas table on another table thinking that "symmetry" would happen.  Well, it doesn't look like it to me.   I guess the flowers were too different.  I don't think I will get the 12 days done.
