Oh yeah. I went there. I only feel this way sometimes. I will tell you some of the things that make me angry this way.
When you curse at or hit your child in public.
When you are in high school and your kid is in elementary school.
When your child has the mindless gaze of the profoundly retarded, but is not retarded, just woefully stupid and incurious.
When you bray loudly at your child in slang that barely resembles English.
When your children are close enough in age that I can't tell which is oldest, yet they all clearly have different fathers/mothers.
When you are fat and hideous and wear an Eeyore sweatshirt several sizes too big, and your child is crusty with dried food residues.
When your child is clever and inquisitive and you are not, and you stifle their every question with “Shut up.”
These are the times when I think you do not deserve to raise a child. These are the times when I think that your child would be better off as a used condom in a trash can years ago. Curse you for dooming your child to an undistinguished life of ignorance, indolence, and squalor.
