Sharku, what you say makes sense too, but it's missing something...
Like I said above, what burrahobbit says just clicks and makes sense to me, however I may be wrong.
These questions that are not answered in Tolkiens books, probably can't be answered at all. Tom may be just a representation of some aspect of Tolkien's personal life, no one knows, and if they do, they haven't said anthing.
So, because no one knows for sure, I will side with burrahobbit because that's what fits the best to me.
It's almost like religious faith really.
