I used to have similar problems. At the end of the day it comes down to a lack of empathy and training, which you must develop. Terse communication is generally a bad thing, because ANY part of it that's misunderstood will distort or even destroy the message you intended. You need to build some redundancy into your message so that people can figure out what you intended. The "empathy" part comes down to understanding and anticipating where and when people will misunderstand (as opposed to saying "I was 100% clear and concise! How could they possibly have misunderstood!?"). You'd be surprised at the number of ways you're being misunderstood every single day. They don't have the exact same knowledge as you, so they can't make the same assumptions as you do in your terse messaging (or they have a very different assumption set - right or wrong), and thus receive a completely different message. And they're going to have a different way of thinking compared to you (that's to be expected - they're different people). So you need to find common ground. Your job is to HELP them understand. Start by getting a few books on business communication. They lay out a lot of ground rules for how to communicate effectively, how to control for tone, how to speak to your audience (use of jargon, etc) and other gems. Another one is the old cliché "How to win friends and influence people". Yes, that book is FULL of gold. When you're getting frustrated talking to someone, it's time to take a step back and ask yourself what you're missing - maybe try another approach to reach that common ground.
