Were all just organisms that are the product of millions of years of evolution. All our emotions come from something happening in our brain that can be pinpointed scientifically. If you are happy it's just your brain sending signals to make you happy etc. That said our feelings are the only thing that makes life meaningful. Parents, school and TV (yes tv raises our kids too) is teaching our kids to have healthy emotions that are appropriate to whatever is happening. The older you get, the more dissociated these feelings get, and the more your feelings are governed by physical(food, sex, etc) things and drugs. We, as humans, are too intelligent to be effected by what other people say and do. You will realize this as you get older. You will turn into an insensitive, sociopathic robot.
