What social convention baffles you?

 I take attendance by having students answer a question.

What social convention baffles you? (previously)

Some people chose physical customs:

• handshakes
• giving someone a hug
• any convention with physical touch

... but overall many people chose social conventions that persist even in a pandemic era:

• small talk
• introductions
• ice breakers
• hi to strangers
• salutations on emails
• texting greetings before th emessage

Some people chose known-to-be-irritating social conventions:

• bachelor/bachelorette parties
• gender reveal parties
• working 5 days a week
• the 9-5 work day

My favorite is the choice to criticize conventions in favor of absolute chaos:

• waking up in the morning

This post's theme word is diachrony (n), "change occurring over a period of time." The social convention diachrony means that handshakes might shift to elbow bumps, or subtle head nods, or nothing at all.
