Telepho-toileto-kinesis

Every time I leave my room only for the faintest moment, I have the impression someone will call me or leave an MSN message. And truly that's exactly what happens all the time. Leaving the room taking a leak - the phone rings. Leaving the room for a shower - someone knocks on my door. When I leave my mobile in my room, it's almost certain that I have 3 missed calls. Why do these occurrences always come concentrated within 15 minutes of a whole day? Might there be a general, secret, undetectable human sense for such things, or is it just a "Mike-specific" skill?
