I'm always surprised on here by people who find the whole school gate experience unpleasant or stressful .. I love it! Or at least I used to.
We moved here when the boys were 3 and 5 and knew no-one. I really enjoyed the brief chatting, catching up, swapping news, getting to know people, sorting out party invitations ...
I now work 8.30 - 3.30 so don't get to the school gate at all now, and I miss it!
