I thought a prime time for contacting the parents is right after school when picking up the kid. Everyone is there waiting, so it's just natural to chit chat, esp when the kids are friends.
I have certainly gotten to know some parents at pick up, but there’s a whole bunch I have not met.
It may be a good time for some small social disobedience to push back to how things used to be
Why do all that, when you can sit in the comfort of a nice warm / cool dry vehicle and play videogames and listen to music?
