+1 ultramarina.

I was flabbergasted when the mother of a child redshirted while born *5* months before the cut-off complained in front of me that some parents (in that case clearly targeting a child born a month before the cutoff) were just irresponsible, and their overly immature kids were dragging down the level of instruction for her own child (who was nearly 18 months older and bright/mature for his age to boot).
