Suppose a a woman has a very impolite, naughty and bad-tempered child; once a number of relatives come by to their house as guests. Before their arrival, mother speaks to her child. She wants to mention some points to her child in order to avoid losing face; are my following self-made examples mean the same in such sense:
- Please preserve our dignity in front of the guests.
- Please maintain our dignity in front of the guests.
- Please save face in front of the guests.
For me they all mean the same excepting one point which differentiates the last one from the other tow; in my view, the last one can be used either before or after occurrence of an event in which one would lose his / her face but the first two are used just before occurring a problem (at least) in my scenario.
