People Should Be Nice

I have a lot of friends because I'm nice. I like people who are nice. Having nice people in my life makes it's wonderful to be alive.
However, there are many people I know whom I dislike greatly. These particular people are mean. I don't like mean people. Mean people are the ones that make this world a bad place to live in. Mean people make me want to slit my wrists and bleed all over the bathroom floor.
If I had the choice, I would zap all the mean people in the world with a Nicerlizer (a gun which turns one from mean to nice) so that they'd change their hurtful ways.
I do not have this choice. Why, you ask? Firstly, the Nicerlizer hasn't been invented, yet. Secondly, I don't have hands. I'm a parapalegic. Thirdly, it's wrong to shoot...
