My personal assistant
I lost my personal assistant for one week. Before that, he was not in talking terms with me. Then he was gone. I tried to find him high and low. He left no trace.
I have become very dependent of him. He keeps track all my appointments. He keeps me company on my bus ride. He bring me news and mails. Some times he sings me to sleep and wakes me in the morning. I was at lost when he left.
Now, he has returned. Eventhough he is still not in speaking terms, I'm glad he has return. My personal assistant, a digital one - my Tungsten T5.
