What would your reaction be if you received this as an email?

I am often aware of taking you from a task that you are only replying to me because you think you should. So I have come up with this A. E. I. O. U. Scale.
Could this be helpful? Or some modification? Or carry on as we are now.

A = I'm good. Anything goes. I can give you full attention. Period.
E = I'm good but with some reservations. Possible interruption
I = Willing but with interruption or possibility of complete drop off
O = Casual comments at unpredictable intervals
U = Bad timing. Later.
