BTW - I wouldn't go so far as to call them "stupid". For many people, they need to be "burned by the fire" in order for their understanding to be reinforced.
But nobody acts responsiblyall the time. We all do stupid things and this makes us stupid at the time we act. Don't forget that deciduous trees shed their leaves because the are deciduous !
All of us do stupid things sometimes, but that doesn't mean that all of us are stupid right ? Hrm.. I heard that before.. Deciduous trees are deciduous because they shed their leaves.. deciduous is just a name..
