Challenge accepted @ceelbomb. I've been alive long enough to have memories of holidays before Internet-or-not was a question.
  1. Decorate your abode.
    Maybe even make something new to add to the decor.
  2. Bake holiday treats.
  3. Read aloud with family/friends.
    The Night Before Christmas, A Christmas Carol, Eight Winter Nights, you get the idea.
  4. Watch holiday movies on TV deluxe style.
    Go all out. Popcorn, snuggle blankies, jammies.
  5. Feed the birds. Especially fun with kids.
    Go outside & collect pine cones. The sort with open "petals" work best. Bring them in & spread peanut butter on them. Roll them in birdseed if you happen to have some. Tie a ribbon to the top. Take the cone(s) back outside. Hang in trees. Wish the birds bon appetit.
  6. Ask a child to explain the holiday to you.
  7. Reminisce about past holidays with family/friends.
    Ask your family (natural & chosen) how traditions got started. Ask about their favorite holidays in the past. I got to know new aspects of my gran that way.
  8. Journal
    No matter how ordinary & boring you think you're wrong.
  9. Hang out.
    Lounge around with the people you love. Talk. Laugh. You never know when you'll get to spend time with them again. Really. That's not just a saying. It's hard fact.
  10. Write an actual letter to someone you haven't seen in a long time.
