How do you feel about weeds?

To me weeds that grow in the vege and flower garden are really nuisance. They cant be completely remove but only their growth can be retarded. They can survice under any bad condition, severe storm, dry spell etc. They can regrow even after burning or spraying herbicidal chemicals on them. We can learn from weeds dont give up no matter how tough our circumstances are. Although weeds bring a lot of problem to us but weeds that growing on hill slopes and river banks can prevent soil erosions.
