Today's Gratitude Item: My dad! Seen as its father's day today, this is a very appropriate item. There are so many great things about my dad that to list them all would take a very very long time. I love his sense of humour, his generosity and his compassion. We have always had a very special relationship and the best thing anyone could every say to me would be that I am just like him!
