I was the baby in my family and my siblings were all much older. I had an imaginary friend named Pukka. Pukka and I played together every single day and he kept me from being lonely. Pukka also went with us everywhere and I would sometimes say (as in throw a fit) that we "forgot" him in the house as we were leaving and we had to go back and get him. My family always indulged me and this went on for years. I am now 44 and lo and behold I am getting mail from Pukka. It appears he is a world wide traveler who has been "friends" with many small chidren who needed him through the years. (I suspect my older brother is up to this, but who knows? Maybe my "imaginary" friend was more real than I thought!)
