I don't know who Murphy is but his law is frustrating lol. I once had more missed calls travelling Belfast-Dublin then I did for the rest of the bloody day hmph
I generally find my phone is seriously busy early in the morning from about 7am-10am. Not that I notice then I switch it off for the sake of some beauty sleep. I also find it is a guarentee that my phone rings like mad the day I leave a city.
