Interruption Frustration

Someone will ask me a question or bring me into their conversation asking for my opinion. Usually I'm met with the same frustration. I can't get one sentence out without an interruption. That's when my role in the discussion comes to an end. Don't drag me into your conversation if my reply is going to be met with your constant interruptions. because you're not really interested in what I have to say. You just want to hear yourself talk all of the way. Once you interrupt me, the conversation ends because you're being rude, ill mannered and a major frustration and you apparently don't possess any self discipline. We can discuss this another time if you like my friend, but the conversation will be over after your first and only interruption.
