I would not describe myself as very involved in my DC's school although I am a minor member of the PTA and have been either a SAHM or in part time work while my DC (now at end of yrs 4 and 6) have been at school so am usually around for pick up/drops off and school functions (less necessary as DC get further into juniors anyway).
But I have noticed some mothers (specifically mothers, haven't noticed any dads this applies to) who are at the school constantly, leading lights in the PTA, on the board of governors, generally helping out, etc. I wonder how they will feel when their DC leave? Devastated or relieved as they maybe didn't really want to have taken on so much. I don't know them well enough to ask so am asking a nosy question of any MNers who fit this description?
