Well, context clue of Bastian calling them 'drunkards'. I'd reasonably expect them not to be kids. Childish behavior aside.

If kids, I'd call them boys. If teenagers, I'd call them teens. ;P 

People old enough to get drunk at a pub, at the very least. Probably young enough to reasonably run away quickly. You could imagine them in anyway you want otherwise. But adult is the answer to the question. xP
