Helping another human being is one of the simplest and selfless things one can do. I know we should all try to be more giving to those less fortunate then us especially around the holidays and if you cant even do something as simple as open a door or help an old person with a simple task I dont know what else to tell you other then
And for heaven sake please be glad you have a house to sleep under, food to keep you alive, something to entertain you other then shooting up a store, and being able to go into some random vent channel and tell everyone fuck you and leave without feeling bad.
