Personal anecdote - Change comes from within

One summer day in the liberal college town of Madison, Wisconsin, my roommate and I were exiting the State Street Taco Bell, when two "train kid" hippies were walking in. A few people in Madison refer to these beggars as train kids because, as rumor goes, during the summer when Madison has warm weather, they hobo-style hop on a train and come to Madison for a while. I doubt there is much truth in this and wonder how many people actually still refer to any of these beggars as "train kids."
These particular train kids were probably older than my roommate and I, and the girl of the guy/girl pair had a small dog with her. She asked us, "Spare some change for a soda?" I replied, "Change comes from within." She muttered, "Fucking assholes," as we walked away.
She is with a guy, possibly her boyfriend, yet neither her or her guy friend have enough money for a soda? You gotta be kidding me.
First moral of the story: One great retort to use against any beggar who asks if you can spare some change is "Change comes from within."
Second moral of the story: Get a job if you have no money
Third moral of the story: If you can't take care of yourself, then you shouldn't have a pet
Fourth moral of the story: Beggars and homeless love hanging out at Taco Bell
