Dear [recipient's name]:

It's hard to believe that another year has flown by! At this special time of year, I reminisce on all the wonderful times I've shared, and all the memories I've made, with friends like you. And I just wanted to express my gratitude for your friendship and caring over the years.

As you know, it's been a very busy year for our family, between moving cross country, having another child, changing jobs, overcoming health challenges, and much more. With friends like you traveling this journey of life with us, we know we always have support through all the twists and turns.

From our family to yours, Happy Holidays, and may you experience much joy and peace, now and always.

Fondly,

[Signature]
