Only the brave bare!

Only those that are brave would talk about experiences that display their stupidity,right? So,in my particularly brave mood,here goes!
I took class on "The 7 habits of highly effective people" a couple of years ago. For 3 days, a group of about 10 of us were imparted precious words of wisdom on how to live life more efficiently. I left feeling mighty puffed and totally empowered to take on the world!
The next day,a bunch of us decided to go to a salad and soup buffet place for lunch. We car pooled,and I drove us all. Eager to implement my newly gained wisdom,I decided that I did not need my purse,would be easier to pig out at the buffet without having to guard my purse!So I took out just my credit card and tucked it in my pocket. I locked the car and plonked my purse in the trunk of the car.
Mid-way through my meal,I realized that I had put the car keys into the purse that was oh-so-efficiently locked in the trunk!
After my colleagues recovered from their laughing fit,one of them called his friend who came and drove us back to work,luckily I had a spare key at my desk,so I could come back to the lunch place and drive back to work!
Well,that was a lesson on being efficient that I will not forget!
