When I was younger, I would call 911 and then hang up.
I assume you were doing this as some sort of prank?
It became more of a habit than anything else.
You shouldn't call 911 and hang up. You are stopping the operators from doing their jobs. Plus, they are able to track your location just from that single phone call and they will send police to check on you.
I didn't mean any harm. Is it really that bad?
You are wasting the time of 911 operators whose job is to talk to people who are having emergencies. While they were having to answer your prank phone call, someone may not be able to get through who is in a life or death situation. Never call 911 unless you really need help.
