It's called courtesy and ethics. look them up.
So your idea of courtesy and ethics is calling people "...stupid...", "...crusty, old 'get off my lawn' types...", saying "I wouldn't want to buy anything from you!" after having completely misreading the post and, bitching because someone didn't give you their phone number because you don't have "telepathy".
Then you want to tell me to "look them up'. How about I don't do anything you want me too and just let you be butt hurt about it. Go cry to your therapist. I can do this all day long snowflake.
