Tonight, after I'd put LB into bed, but before he'd fallen asleep, a helicopter flew over our house and was fairly loud.

LB got out of bed and told me that a train had just driven through his bedroom. I reassured him that a train had indeed NOT done that, but that it was just a helicopter flying over.

Although, I think he'd have been THRILLED, if a big frightened if one had driven through his room. He currently LOVES trains.
