Politeness and impoliteness clearly involve choices, both linguistic
(how you say something) and non-linguistic (whether or not you decide
to help/hinder someone or praise/criticise/show interest in them).
Below are a number of different expressions that could be used in an
attempt to achieve the same effect (i.e. by interfering with the negative
face wants of someone who smokes cigarettes – or in other words
to perform a Face-Threatening Act [FTA] towards them).
First, arrange the expressions into what you think
is the correct order in terms of politeness / impoliteness by dragging
them and dropping them into the scale below and comparing your ordering
with what we think. This exercise should have the positive benefit of
being more aware of how to be more greasy when you need to!
