I'm well past that age, but I can't think of one thing I've done or been relied upon to do every year for 25 years. 25 years ago our elder son was born, and then a month and a half later we moved to Shiloh. So, for 25 years, since September 1st we've lived in Shiloh. We've changed; Shiloh has changed.
Jack has been leining on Yom Kippur for 25 years. That is totally extraordinary.
