Hopefully we won't have to listen afterward to the failures whine that because some of the students got diplomas and others didn't, that the graduation ceremonies were inherently unfair and should be banned altogether.
Oh but you know that will eventually be the case.
I think further that the school system should see that Tiffney and her friends get jobs (even though they can't read, and critical thinking other than what brand of beer to buy is beyond them).
The school system should be required to employ these people for at least one year as aides and secretaries and the like.
Let them reap what they have sown.
