My girlfriend is paranoid when it comes to security. At worst, she will press the clicker at least three times. Then, from within the house, or from whatever location we happen to be in, if the car is within line of sight through a window, she will press it just one more time. Sometimes she even insists on running out to do it - I usually volunteer to do so instead. I've more or less gotten used to it. At times I wonder whether she does it just to irk me. She is considerate about being too noisy though; she's never done it when it's late out, or when it might annoy someone that might be sleeping.
