You can say "shum" after a person coughs to acknowledge that you are not bothered by the cough, and that you hope they are okay

It is pronounced: sh-UM

It is inspired by the calming "uhm" sound that is soothing to others when they are coughing

John: *coughs*
Henri: Shum to acknowledge John's cough
