Our LORD'S Birthday.
Or an "Act of Kindness".
That would remind us all what this season is all about!!
It begins with 25 cards and 25 envelopes
At the end of each day in December print a photo ( you can do this at Fred's or Wal-greens quite easily), write a little note (or get one of the kids to write a note) about something that happened that day, and mailed it off. Simple and I think, very meaningful.
