Cautiously enthusiastic

Joelzy seems to like his three mad cousins. 
He can definitely see the fun potential to be harvested from that mad lot. 
He is not always too sure though what they are talking about, in their frantic Dublinese. 
But he can definitely see the fun potential.
He finds them fascinating, in a thrillingly dangerous sort of way. Like a jerrycan of petrol left in the midday sun. Or a rottweiler in a petting zoo. 

He will follow them. 

But best to keep a safe distance for now.
