When I went to my friends house once she called her parents when they were a floor below her.(simular to chrissycat12 said) Also once she called her parents when they were just right inside when we were in her backyard,why waste your minutes when you can just walk inside??? I've also seen people at fast food places talking on their cells while their working the register. I've never seen people talk while their on a horse (they might have them in their pocket) but, I would never do that what if the horse goes crazy and starts galloping and you lose control. I have seen ppl smoke while their on horses, which is the soo stupid!!!
