I called a friend of mine who I had not spoken to for quite a while. These things happen; both of us have our own lives, worries and things to do and both of us do not really take the time to sit and call the other one. But last week I did take some time and called her. Apparently she had reported sick at work for a while already as she was suffering heavily from joint complaints. She had not done anything particular and the doctors didn't really know why this had come up so sudden, because usually her symptoms would come up gradually. Anyway, she was very happy I called.
