Not all do that though, Prunerz
Our PTA was quite good, the last chairwoman got it from a one woman nightmare (NOT the fault of the lady herself, she was great but bad things had happend before i think, she got lumbered with a small committee who then ended up with other things on their paltes....). we weren't cliquey. how do I know this? becuase I am not in cliques, ever, I am alst one standing at PE girl, the original. But they worked to find ways for all to help- I can't do seling,I can however make letterheads and rite letters/ take minutes, so I did that.
Our events were popular also; minimum number so as not to be annoying, and always well attended.
We used to mett weekly for coffee in the mornings, as it suited most of us (my Dh worked nights,chair was a Vicar who diod evening metts, etc etc)..... so people complained we alienated them by holding daytime meets, we arranged one (my Dh took a night off- and no show).
I do think when it comes to PTA's the problem with somepeople is guilt; they're so convinced that they should be doing it they find amyriad of excuses why they don't, be far better if people could just feel fine about what they *do contribute and get on with it
Afterall, whats the point ofa fetewith 200 stallholders and no customers?
Do what you can, and feel positive about it
