Why do kids find the need to type their homework in yahoo answers?

You know, not all kids do that because they are lazy. It's because they don't have anyone to help them with their homework. The first thing that I do when I get home is to do my homework (if i can't figure out the answer in 1 hour, i'll go ask my mom), and if my mom doesn't know the answer, I'll go to yahoo answer. But I only had to go to yahoo answer and ask a question about homework once.
