Or that it's simply as dumb as a brick and would be better off being used as one. Kids are like all other people: some are more or less functioning, a few are intelligent, a very rare few are brilliant, the rest are bricks of dried shit. This is a reality of life, but parents can't accept that their precious little snowflake could be any less than this century's great genius. Once upon a time they would insist it was "misunderstood" or "simply too far ahead" or an "indigo child". Now they're all assburgers.
I wish teachers (those who are worth their salt, and those are in diminishing numbers) would grow a pair and tell the chopparents: "See, your kid is so useless it ought to be recycled as pet food. It's not brilliant, it's not a genius, it's a shit windowlicker. Or rather it would be if it could tell a window from anything else. That's how stupid your shit kid is. Did you try to abort it by any chance?"
Yes, that's the sorry situation. Chopparents who can't accept their subpar progeny is two IQ points too low to be yoghurt so they try to pass them off as smart windowlickers. Guess what: windowlickers aren't smart, or they wouldn't be windowlickers.
