Is Mule your real name

No

Why are you called Mule

That is my nickname

What is your real name

I cannot remember

That is an unusual name

But why Mule

Because I am the offspring of a Jack and a Mare

My sister is called Hinny

A nickname

Yes as she is the offspring of a Jenny and a Stallion

But if you forgive me you look like a girl

It is a trick of the light

But I have known you for a number of years

I assure you that it is trick of the light

You have a female body

When we swam yesterday you looked like a woman

You had all the curves in the right places

I am a Mule I assure you Jim

Do you have a tail

Yes

But I did not see it yesterday

It does not like sea water

May I call you Margaret

If you like Margaret is a pretty name

Was my fathers name

Then I shall call you Maggie instead of Jim
