children of above-average age

Children of above-average age,
please do what I do and don't say 
I ever or never warned you wise, 
or otherwise you can just choke 
on lies and grow up, bones and teeth 
all whitening strong. If you'd do 
as I say, you'd be there all along! 
But you've lagged behind years 
of maturity now. I suppose 
it will catch up with you 
somehow.
