three kids, three floors

i recently asked my friend,
who is one of three kids,
"how did your mom do it?"

she answered,
"oh, easy. three floors."

"three floors?"

"yes, she would yell at us,
you - stay here!
you - go downstairs!
and you - go upstairs!"

genius.
except for one problem.
i only have two floors.
dang.
