When R and I got married, we started a tradition of buying a Christmas tree ornament from each place we visited as a family. I don't know if when he suggested it, R knew how perfectly it meld our separate traditions into something uniquely suited to the three of us, but that's what happened. Our tree is like this perfect representation of our lives - what we came with, and what we added together.
We don't really have room for a tree here and I didn't think I minded it last year when we just skipped that part. But this year (I think for obvious reasons), I was really longing to unwrap those memory-laden ornaments and hold them in my hand.
