What is up with these kids going door to door selling stuff?

So its about that time of year, where teens go door to door selling stuff. Now I'm not the one usually opening the door, I usually pretend that no body is home, but my dad usually opens the door. Then he gives them a lecture about goin to the military for money or getting a job for like an hour( closer to 30 minutes) then proceeds to give ME a lecture about the same thing! WTF, I hate these kids, why can't they just get a job or something??? I have a job already, selling portraits, I make alot of money from it (like 50-200 dollars a week) just by drawing and painting. And just now, my dad gives one of them 5 dollars... WTF, im the one goin to high school with kids like these, and the only ones that care about their education are the ones getting scholarships and working... WHAT THE HELL???
