Guessing Game

She lied, but

Only once per day.

Never more, never less.

Obviously, the hard part

Was figuring out when it would be.

Would it be the

First thing she said?

The last thing?

Somewhere in between?

Statistically if she said ten things

In a day, there was a ninety per cent

Chance any given item was the truth.

It was nice on those occasions

When I could verify what she had just told me,

For at least I knew that was the truth.

However, did she say it true because

She had already lied and she had to,

Or was she saving her lie for later

And she wanted to?

And if she ever told me which one it was,

Could I believe her?
