Good answer, Denis.
I'm sure the Russian says "That's children for you, though the majority of adults have a passion for fresh hot bread," I would reword that a bit in English. For one, you can really use 'though' like that ('tough' here would be used to nuance the statement about children; it can't be used to contrast it to the adults you introduce thereafter). Also, don't use "majority" unless you really have to (like when you're talking about voting or something, or want you want to be specific about the overwhelming numbers). "Most" is much better, in the majority of cases. :) I'd put it like this:
"That's children for you -- whereas most adults know how to appreciate fresh hot bread!"
