Surprise was in Ethiopia and everywhere . (Like people be saying የማረግልህን አታውቀም or ሽልማት አለህ and lovely mother will put something lovely ደብቀው )and this pretty much proves it was noth something that came by globalization . I did notice in Ethiopia We use it mostly to show love and to show generosity .
Surprise is when something happen out of the way we expected it or when U get a response toward something what our brain knew in a different way.
E.g we see things by our eyes in 2D but we understand in 3D . Meaning If i see a car ,i don't have to look into it to know it got a driver my brain will just make the image . But now according to new technology development If i see a car with no drive i will feel surprised.
