Naval subjects do tend to involve drift and can become rudderless to and fro's. At least this drift doesn't need to be
propped up by any stern warnings, so those involved can take a bow.
(Wearing long johns so I don't need to be told to remember my coat on the way out........)
Thread-drift happens when someone offers a bridge to another topic, others go with the current, and still more follow in their wake.
Hold the door, please, I'm right behind you.
