Presentation was not a big deal for me. I have done it so many times without flaw. However, last week presentation was a big different. That Wednesday, I should perform presentation in front of the owner of the company. That was the first time for me to stand up in front of the highest person in my company. I got a little nervous but I can keep myself calm because had prepared everything.

The opening was run out without problem. I had the confidence and I was sure the materials are checked. Unfortunately, I made mistake when I was played the video. I supposed to play video about our research in the next construction constructions site but the video I played was my kitty playing a yarn ball. People were suddenly laughing that time.

I was so embarrassed. I apologized, and quickly changed the video. The laughing last long until my boss stop it. I was so blessed that my boss is very kind person. He smiled and asked me to continue my presentation. Apparently, my boss love cat so the video did not bother him much. Thankfully, the rest of the presentation was run well without problem.
