Schedules and being on time

I'm a bit of a stickler when it comes to being on time. If I tell someone I'm going to be somewhere I'm there. If the occasion arises when I don't show, then something has gone horribly wrong.
I'm active in a community shop called the port city maker space. They have all sorts of classes and workshops to help everyone from the technically challenged to seasoned pros gain useful knowledge.
They also supply tools and work space to aid people in creating whatever they want.  There was a suggestion that we have a group build, to gather all the member who would like to participate and combine our knowledge to achieve some goal.
We decided that we would build a 3D printer. They are all the rage with the techno suave right now.
Our first official meeting was going to be april tenth but due to some scheduling conflict's they moved it one week later.
Being the type of person who hates to be late I left work and drove the hour up to the shop and I was early, about twenty four hours early.
Now let me tell you how important it is to read the schedule correctly.
