I picture it as a fist going like (if a fist could talk) ummmmmmmmmmUUUUMMMMMMMAAAAAAAAA-bump(softly) and slightly pushing the thread up but only like an inch or so, despite the unnecessary sounds. Then the thread settles into its new position one notch above where it was before, all disheveled. Then it goes back to sleep before somebody wakes it.
Alternatively, the thread is smacked so hard it smashes through all the layers of threads above it and reaches its new position at the top in a matter of seconds. It then stares down at all the threads below it in their broken state and begins to feel bad. Then he wonders “Oh no! I am so high up now, what if I fall??”
The stickies are there to cushion the blow.
