I grew up with the Jewish goodbye.
In a group setting, you need to say goodbye to everyone, or at least everyone you know. If you miss a person, it might be rude. They might wonder where you went, whether you’re okay. They might question whether they’ve offended you, whether there’s something wrong. “Where did Andrea go?”
At least, these are the sorts of thoughts we have.
