My daughter thinks that my father’s is the best. When she called him to let him know (after she told me to call him), he wasn’t there. He called back in a bit saying that he was so excited about the news, but since no one was there for him to celebrate with, he went downstairs to the exercise room to do some push-ups!
But I think that my son’s is the best. He wrote in an email after our daughter sent a photo of her new precious baby girl:
[Our baby] was so excited to hear about his new cousin that he pooped!!!!!
Pure quiet gratitude.
And a blogpost here.
