demanding friends

I've got friend who lives in Kuala Lumpa and the only time I ever hear from him is in the middle of the night when I've just gone to sleep..he never seems to learn about the time line...it's always grand to hear him, but I usually leap out of bed thinking it's some terrible crisis when the phone rings at 2.00 or 3.00 in the morning......has anyone else got a friend like this?
