Busy. A horrible word. It suggests a spiritual disease. A bore is someone who remarks how busy he is and with what activities. I think "busy" means being egotistic and arrogant - believing the world needs me so much. It means being inhospitable:
I regale you with how much work your presence demands of me, how intrusive you are.
I play God. I imply that you are less important if you are less busy. It's hard to expunge "busy" from the vocabulary, but it helps to remember its use is offensive.
