sunt pueri pueri

saluete omnes

I remember a former teacher of mine quoting this in Latin:

sunt pueri pueri pueri puerilia tractant

I am just wondering if the conditional clause does not need a subordinating conjunction. Any thoughts?

gratias uobis ago et diem bonum opto

I’m not sure where there is a conditional clause (as written); it seems to me like two sentences joined without any punctuation:

sunt pueri pueri; pueri puerilia tractant.

Boys are boys; boys do boy things.

Is there another way of taking it that I don’t see?

I take it the same way. I don’t see why a conditional would seem more likely.
