When the story was recounted, the person said, "We wish you could have been the mohel."
To which I said, "Then why didn't you call?"
"O. We thought you wouldn't be interested in traveling."
Certainly there are times when my schedule does not allow for me to make a trip. But I enjoy traveling for a bris, and I make every effort to to attend the Brisses that are a flight away! because those trips are the most fun for me on a personal level.
