Why did I say yes?

For those of you who know me... I tend to have a problem with saying yes. Like as in... "Oh, that sounds cool, count me in." "I'm in like a rat on a cheeto." "That's a need... I bet I can help out with that." "I've always wanted to do something like that." You get the picture. However, I'm learning to say no or not jump in with yes and ask if I can get back to people with my answer. Hopefully this learned reticence (in a good way) will protect me from getting roped into doing all the work for a shower that I'm not even hosting, doing the dish pit for a banquet of 250 after a 12 hour day or doing childcare in the toddler room (full body shudder) on Easter weekend when everyone with a toddler who has significant separation issues and anxiety decides to show up at church. But I may not be there yet. I got talked into teaching people to knit, which I love to do. After I realized that I had said yes, I realized that I had said yes to teaching people who are at a conversation cafe to learn English. Ok... why didn't I think about what I saying? I talk fast and am always having to consciously tell myself to slow down. And I start talking faster when I am excited, passionate or nervous. Did I mention that I always test as being high on the Big Picture skills vs. minutia details-which happen to be very important in knitting. See where this is heading? So... if you see a group of new Canadians wandering out of a conversation club with wierdly cast on knitting, lost looks and tears in your eyes, you'll know that all my fears have come true. Why don't I think before I say yes?
