A Message

Today is my birthday.
And just now, I opened email and found that there was one email from my mom. She said, "Happy Birthday to you! Today is September 12th. - We can only support you from far away now, but thank you for coming into the world as our child."
I got some presents from a friend and was treated to lunch by another friend, but this email was the biggest present to me.
In the future, could I say "Thank you for coming into the world as our child." to my child when he/she grow up?
I certainly have to say it... because that phrase filled me completely. I was filled with so much joy that I couldn't stop crying.
I thanked to my parents and thanked to the email system that brought me this message.
