I understand that, to you, life revolves around what you plan for the 30 minute 2nd grade Holiday Party. I can tell you are so brimming with great ideas that you didn't think twice about scheduling a meeting to discuss it 3 weeks ago. You are very task oriented and lets just say it, bossy. I get that.
But, can I interrupt you for one minute to just say...relax...
Let me also take this time to mention that though you were very upset I couldn't attend the meeting (that was held two weeks before Thanksgiving) some people have a life and 3-4 weeks is plenty of time to plan a generic "holiday" party that will take approximately 30 minutes at the end of the school day.
Also, in this "cyber age" a physical meeting during a holiday month with all of our preschoolers and kindergartners in the middle of a packed Starbucks isn't usually necessary. See how I'm communicating with you here on the computer? You can do that for the party, too.
In closing ... relax, get a life, and email.
