Two similar

Somw while back my mobile operator decreed that I, for unclear reasons, needed a new SIM card. This of course required me to reconstruct my phonebook. At the time I did not make the connection, but it was at about then that Troll, trusty member of the Posse, went incommunicado. My texts were not responded to and I only got a voice-mail prompt when calling. After a couple of months we started to get worried—what could be wrong?
Eventually I had a brainwave and googled up her office phone number. She answered immediately with her usual cheery “Helloo!” It turned out that her mother not only lives on the same street but has the exact same extremely uncommon name. Apparently she had been utterly consternated by the barrage of invitations to various mysterious activities by an unknown man. Ah well, that should be suitable punishment for the lack of name imagination. And we have Troll among us again.
