Oh $@%t!!

Jonah was playing the ball maze game on Shabbat and all the sudden he says "Oh Shit" (it sounded like "Sheet") So I said excuse me, and he said, very matter of factly that the ball fall off the rail. He had no idea what he said was a bad word. I realized in Hebrew, shit isn't considered a bad word at all, from what I gather it's pretty meaningless. So the question is, do I tell Jonah that what he said was a bad word, and bring attention to it, or do I just say that he was speaking hebrew and that it's OK for him to say it.

At the time I didn't say anything, as I didn't want to bring the attention
