We've just had the last of our house renovation areas carpeted, so TWO is now distracted with how good it feels and it seems the argument has passed....for the meantime.
BUT, Hatch2/Batch2 ( Campbell - age 24 ) came home today and I asked him the same question - he enlightens me that he took Japanese at school ( which now explains the girldfriends ) and "Dad - there's the proper way to say it like they do in Japan and that's.....On ( as in on ) - kyeerr. The "O" never resolves to the O as we know it - it more tapers off into the valley" ..."Trust me - I took Japanese"

Guess I'll gather more knowledge by the time he gets to age 36
