Pros and Cons of Teaching Adults vs. Children

I have been teaching English as an ESL teacher for over three years. The first two years I taught adults from ages 20 to as old as 60. This was in the Czech Republic. After that, I spent a year teaching young children ages 5 to 11 in South Korea. There are obvious cultural reasons as to why I thought the children were more respectful (South Koreans as students are generally more respectful towards teachers, etc.), but I was also surprised that I would actually enjoy the experience.
The great things about teaching adults is that your humor is easily understood and that you have freedom to glaze over adult topics (i.e. news, taboo issues, adult matters) that may not be understood or unknown to the young children. You also have the reassurance that the adults will remember not only what you taught them, but will remember you as influential to their English learning career.
One of the more negative aspects I can remember about teaching adults is the fact that the are generally not under as much pressure as they might have been to learn when they were children. They may not have a parent to motivate them to do their homework or study for a test. When an adult is late for a class, their excuse is seen as something adults would understand (car broke down, or just a simple apology), while I rarely have taught an adult who felt as guilty as my young children did for being late. Additionally, more often than naught I find adults can be very boring in describing their personal lives. When the typical "What did you do on your weekend?" question would come up, the married adult students are the ones who would generally say "Oh...nothing, just watched TV, etc."
My Korean school children on the favorable side were very motivated to learn. There was a true competitive spirit to learn, guilt was felt if a mistake was made, and overall a great attitude for learning was present. The students made great efforts to learn, and this was backed by their parents in encouraging them to do their very best (or most likely be disciplined at home). Lastly, I could use any word combination and even say things that were just plain silly and the kids would laugh as if I was the greatest comedian they had ever heard.
Negatively, it was slightly discouraging to know that these kids may not remember me when they become older. They also were very immature to voice opinions about mature issues, so those were left of out conversation, and that sometimes made the conversation field of topics limited. Of course, behavior issues were dealt with more frequently in class, which sometimes wasted time for learning.
In conclusion, I think a teacher should try teaching both age groups to really get a feel for what they prefer to teach. In general, I believe teaching adults is what I prefer for my career, but I am happy to have experienced teaching children.
