Heard while Covid is still a fear:

In a public convenience a mother saying to her daughter of about 3y, “Don’t touch anything!”

(Good luck with that!)

And near the sea between a father and his son of about 4 or 5y:

Boy, “Can we swim today?”

Dad, “No. They’re discharging raw sewage.”

(Well, I hope not just there by the pier as the first stage in the local ironman triathlon starts with the participants diving off that pier next day for the swimming!)
