.the question.

can be a difficulty

to say that we do not know

the answer.

that we have to count

check

count again.

that we get distracted

disturbed by other matters

then

come back. miscount

again.

it is not some thing we can google

so we have lists lines and rulers.

when all is done we sign and date

admit we do not know the answer

maybe start again.

sbm.
