Don't say you're sorry when you're not sorry! You didn't even look up to see who you bumped into! What if I was an old lady? I could have fallen down and broken a hip! I could be lying on my back in some HMO, my lungs filling up with phlegm till I'm on life support, draining my family of every last cent of their inheritance while I asphyxiate on my own dried half-hacked mucus! No, don't say you're sorry when you're not sorry."
