Nothing too untoward yet -- just some strangers doing something strange.
Dylan's natural curiosity had him absolutely fixated.
He couldn't figure it out.
Then he heard a rumbling sound and he looked at me as if to ask "What's that?"
When the rumbling turned into a downright CATcophany ...
... Dylan's eyes widened in fright and his ears went all wonky!
"I doan care wot it is anymoar, jus' make it stop!" he begged.
So we went inside and shut the door behind us.
Case closed!
