sometimes, it can be quite irritating when someone asked you to calculate something for them and u'd forward them the results but they do not take note of it. and they'll ask you the same question days later. gave them the answer and having them to ask you again after a few days. cant they EVER take note of it no matter how busy one can be? imagine telling them the same thing not once nor twice but as many as 3 - 4 times.
