A family card party.
One of DH relatives, who lives back east, is turning 80 next month. His daughter sent us a card (snail mail) inviting us to his birth day by sending a card, (snail mail)for his "card party".
We'll send a card, and DH will write a small note with a memory from their childhood together.
I think this is a totally cool idea.
And while we are talking about celebrating long distance, a friend of mine could not make it to her daughter's house for xmas, so they celebrated via the computer and video. The grands opened the presents, showed them to grandma, then grandma opened her presents and showed them to the grands.
All kinds of ways to connect.
