Sounds like this one's a dead end but for the sake of your progress as an effective communicator with ANYBODY in life, consider putting some more thoughts into your messages.

You don't tell a boss, "Yes, I'll get on that account. It's just something I have to work on. I'll give you a call when I get a chance."

You tell him specific information instead, "Charlie from the ____ firm is crunching numbers now and I'm making some slides. I'll meet him tomorrow first thing in the morning and we'll be ready for the proposal before lunch."

You've got to figure out a way to put a smile on people's faces with specific and positive information. Your message above was short but far from sweet.
