I thnk, Hazbeen , that you can add a few new moves to your repertoire, for example:
The sniff. Not so much anything to do with checking if anything has gone "off" or a runny nose. For a master class in perfecting The Sniff, check out Linda Snell in "The Archers"
The Shoulders this also incorporates some neck movement, think of it as Pilates for the quietly indignant. Lower and straighten your shoulders, while raising your head and elongating the neck.
Once perfected, these moves may have some effect, but if they dont, you might like to consider the Brisk Purposeful Walk For maximum effect, this should be done wearing shoes that can be heard as they make contact with any floor covering.
Slippers will not have the same impact, and could lead to tripping, which completely ruins the message you are trying to convey.
Once mastered, these moves can be combined.
Hope this helps.
