I agree with twm - and it made me laugh, as did 2 down when I realised who the 'educationalist' was. (misguided? boring? dies? I guess Araucaria's not enamoured of him either!)
Ironically, I got the LHS first, and I'm still having problems on the right.
22A Auxilliaries do what the are supposed to (B_H_V_)
presumably 'behave' - but why 'auxilliaries'?
24A Break down to earth in an insincere way (H_L_O_L_)
pres. 'hollowly' but again why except definition?
Nice to have Araucaria back.
