Hi there! I've removed the should I part of your last paragraph as it's off-topic here. Doesn't seem to me that it's doing any harm to your post, please let us know, thanks. — OldPadawan46 secs ago
As a parent, I wouldn't want to discuss how I teach my child with a total stranger. If it was me, I would like to know what I can do to avoid these discussions in the first place (while taking my kid to a coffeeshop), if possible, and second, how to get rid of these strangers with the least possible effort, and with no impact on the child. — gnasher7292 mins ago
