This kid just doesn't have time for your bullshit. It's obvious that Dave is really fucking cool; he jeered at John's inability to set up his Captchalogue Sylladex when John asked him for help and berates John's interests constantly. Dave is much more skilled than the other two characters, who either through their own cluelessness or admission are less capable than him.
Aww... right now we're dying for a special web browser that lets us reach through the Internet and pat your fluffy little feathers. Someday, you're going to grow up into a big duck and migrate back and forth between two homes (that's right -- not only will you be able to fly, you'll take extended vacations every year in a warm southern climate). As a baby duck, though, your life's not quite as luxurious. Some baby animals get to snuggle up to mom and take it easy until they get used to the world, but ducklings can swim and feed themselves as soon as they hatch. The mama duck basically leads them to water and says, "OK, do your thing." Please take care of yourself, OK? The world is counting on your cuteness.
You are inspiring and uplifting. You bring out the best in people, through both nurturing and challenging them. You always can see the big picture in life. You are very philosophical and deeply spiritual. You understand people, and you can look at their lives objectively. You can help others grow and heal. People feel comforted by your presence. You help them gain perspective on their lives.
