Just because you pontificate/write a novel doesn’t make it true.
I guarantee you, if you go the ND alumni website you will not find a single member who doesn’t have at least a degree from ND. The idea that someone who took one class would be registered officially by ND as an alumnus is laughable.
Better yet the idea someone interviewing for a job would try to claim alumni status for Notre Dame or any other school is even more laughable.
Could give a snit about your dictionary definition. I am referring to real life.
