Also kids learn to rhyme words around preschool and will invent the bad words anyway while babbling away. Most people give them a pass on this I think though.
We let our son know when he found words that aren’t appropriate for public use both when he “made them up” and when he heard people using it in songs or other people talking, or mom and dad in traffic occasionally.
He got the concept right away, but he’s also a great kid who wants please most of the time, especially at school or in public.
We were getting on a flight to leave Boston that afternoon. It was a little weird in the airport, but the full situation hadn’t set in yet.
Ironically the flight home from LA a week later was more stressful, as there had been the manhunt and nighttime capture of them at that point.
My brother was house sitting for us just a couple miles from MIT and had to be locked down, but it wasn’t the direction they went after the security guard incident. I think they ended up in Watertown if memory serves.
