When you are small and svelte and feathery, you probably enjoy going IN and OUT of things.
For instance, say there is a plastic bag and it appears to contain your favorite breakfast cereal.
But the large featherless being is busy and isn’t picking up on your (un)subtle hints that you would like her to spoon some into your bowl (inexplicably, she appears to be preparing her own breakfast – go figure).
So the most expedient route is to just go on in yourself to get it.
