Be aware of the humor each day.
Make it a habit for everyone in your family to share at dinner something funny that happened to them.
My husband studies comedy---almost every night he watches Faulty Towers a British comedy.
Laugh about funny times---when I went to see the daffodils this weekend. My daughter said they were dead. (They were in full bloom!)
Finally, be a good sport when a blog entry and images don't work. Someone maybe playing a trick (hmmm).
