while in uganda, this is the look i received from countless very young children. as it was later explained to me, for some, it was their first time seeing a white person. (only once did my appearance make a small child -- less than 1 year old -- simply burst into tears)
most other children (older than say 2 or 3) would yell "muzungu! muzungu" without fail any time i came into view (which was often as i walked and ran the same road for many days at a time).
fun fact: "muzungu" is a word meaning ‘white person’ in many bantu languages of east, central and southern africa. the word stems from a contraction of words meaning 'one who moves around' and was originally coined to describe european traders who traveled through east african countries in the 18th century. the word became synonymous with 'white person' because of the traders' complexion. (in other words, it is a well-intentioned term directed at most every white person where i traveled; if you plan to travel to certain parts of africa you can except to hear it often!)
