Some duds camouflage amongst a large population of duds and others they can't hide stand out like the dog shit. Duds are becoming a problem to due to society accepting behaviours that we did not use to tolerate. By people becoming complacent with negative or bad behaviour the dud ways of the dud are igniting pain, like wild fire it is insidious, deadly to loving soul. People who don't realise the dud is brurning them often end up receiving a fatal blow from the duds black Saturday devastating dud deeds.

The acceptance of dud behaviour will certainly see you burnt not once but many times by a dud. The Dud population is growing like the rabbit population in Australia the mass rising of duds is becoming a scourge in all aspects of micro society. It's phenomena first became aparent with the rise in Methamphetamine use abuse and misuse.
Dusty is a Dud. What a piece of shit. With or without knowing he completely disregards things important to normal people like respect or empathy to another's feelings. He does things continuously to benefit himself and in doing so hurts anyone that tries to show him love or kindness. He sold me a blanket to keep me dry. The blanket was wet. Dusty doesn't care. He is a dud .
