A_298 - I share the following gestures that can be used in every nation of the planet in which they are known by people both in working environments and interpersonal ones :

• Finger over mouth, even smiling, while watching someone that is watching you --> Meaning : please, stop talking.
• Finger touching cheeks repeatedly while we look at someone that is looking at us --> Meaning : i would like a kiss from you on my cheek. (not in working environments?)
• One hand on the chest and the other in front --> Meaning : i need space, please leave me alone.
