Help your pal manage his life
Do you have a close friend who is always busy in some unavoidable errands?
Sure, you have one.
Whenever you call her, she will be in the middle of something important and she doesn't have time for a 2 minutes casual chitchat.
Whenever you meet him outside his office or in his house, he is ready to run away fast to complete to do something or to complete the draft of a proposal.
Don't think that they have reasonably taken many responsibilities... They are just mismanaged. They have just mistaken their responsibilities.
Help them plan their time and duties. It will be a great help to him/her and the society in general.
