I learnt a phrase recently, that is to lay it on the line. I understand that means to be honest, to tell the truth without euphemism
but what i really want to do is there any meaning for on the line ? or it's just practice or english usage.. as i am a non-native speaker so i don't really understand why these words make the sense of to tell the truth without euphemism
Also, i would like to know the meaning behind the proverb
tell me and i will forget
show me and i may remember
involve me and i will understand
thanks in advance!
