Kanye West interrupting Taylor Swift at the VMA's
I disdain when people interrupt me,it irritates me! I was sitting at Cafe` Brazil the other day with one of my friend's. She had just finished telling me a story, so I began to tell mine. My friend then interrupts me in the middle of my story, she proceeds to tell her own story and then she says in an uninterested tone "continue on with your story".
If you are worried you will forget what you have to say, it doesn't mater. Quietly listen to what the other person has to say. If there is any quality people appreciate in a person it is being a good listener.
So people who do this its time to shut your mouth and open your ears. Besides if what you had to say was important enough you will eventually remember.
