1) direct request with no politeness strategy
e.g turn that music down, its too loud
2) positive politeness strategy, often using hedging
E.g I love the band you're listening to but your music is a bit loud, would you mind turning it down
3) Negative politeness strategy , avoid ordering or imposing
e.g I'm sorry to ask you this but can you turn your music down
4) indirect request, avoids being explicit , more cryptic
e.g I really love this book I'm reading, shame its so noisy on this train.
5) inaction, not reacting at all in order to avoid confrontation
