Teachers need to be trained to look out for emotional problems and help the children talk about their experiences . In Athens , public slaves were trained to look out for counterfeit coinage , while temple slaves acted as servants of the temple 's deity . Are n't they supposed to be specially trained to look straight into the sun / Son without protection and without blinking and without going immediately blind and without suffering from those weird little residual tracer thingies in the back of their brains for the next 20 years ? Every Norwegian has been trained to look right through art . Guards are trained to look menacing rather than discreet . Add an azalea or other plant that has been trained to look and grow like a tree .
