Yesterday I got chocolate from some students. All girls because yesterday was Valentines Day and in Korea it is not uncommon for girls/women to give boys/men some chocolate. On White Day (March 14th) it works the other way round but with candy. A gift from a kid is fairly rare for me. I get gum or small snacks from time to time (Koreans are often willing to share food) but chocolate or anything else is something I don't usually get, nor do I expect any gift.
I don't teach Kindergarten, am not female, don't teach in a public position and am not a pushover with my students. From my experience of five years in Korea it is those teachers who get gifts so to get something was a nice surprise because it was unexpected and probably undeserved. Some kids here are really generous, interesting, wonderful children and it is those that I will miss when I leave and not the chocolate.
