Let's Talk About Miscommunication

You know how you are use to people's ways and you build up a mechanism that helps you filter through the bull crap, well that can lead to miscommunication. I received a notice to attend a meeting from an organization that tends to give short notice when scheduling meetings. My filter was in full gear and I assumed when I saw the word "Tuesday" that it meant today at 7pm. I realize this was a conflict with the business of my education, so I referenced the meeting in an email to my professor stating that I could not attend class tonight because I had to be at this meeting. I literally made a copy of the agenda and left it with my classmate in order be accountable to both my class and the group I was meeting with. I arrived at the meeting location at 7:19pm to meet complete darkness. No one was there, at which point I pull the agenda from my bag, remove my filter and I read the 2nd line "on Tuesday, November 18, 2008, 7pm"WTF I filtered the wrong information. Now I will miss two days of class because the meeting will be the following week.

Expectation: To attend a meeting
Deviation: I did not read the notice fully
Result: Wasted time and missed out on valuable class time for no reason and will have two absences instead of one.

Miscommunication: SENSELESS
