I don’t like to share cookies

Sharing is caring
That’s what they all say
I have no problem with that
I can share all through the day
My time and my treasure
Are yours for the taking
What’s mine is yours
Except when I’m baking
Cookies to be specific
Their mine. All mine!
Just kidding. You can have one.
I’ll have the other nine.
I know it’s an issue
That I have to work on
But this time let me have these
Until they’re all gone!
