Translation of "casual" into Bosnian

Some people don't put stock in them and they can be casually cruel with them.

Neki ljudi ne ulažu u njih i mogu da budu povremeno okrutni prema njima.

And yet, to a casual observer, it would appear that you do very little around here.

A ipak, slučajnom promatraču bi se činilo kako ti jako malo radiš ovdje.
