In my readings for my honors project, i've come across a connection with objects and tragic events (example 9/11) it then crosses over into the memorial, gravesite, etc. Why do people leave behind things like teddy bears, notes, etc, are they intended for the deceased/missing? Is it the publics response to tragedy, expressing emotions/ feelings through leaving objects? After tragedy people have an urge to gather. 

Something terrible happened to a family near by and immediately people started leaving behind flowers, stuffed animals, notes, candles, etc.
