Overheard at my house...
Mom: That is the Star of David. Hitler made all the Jews wear the Star of David to identify them.
Anson: Did they get killed?
M: Not at first, but eventually they were rounded up and sent to concentration camps where millions upon millions of them were killed.
A: Was that because they weren't concentrating?
For the record, I did correct him, but only after a hearty laugh.
