Ball python

I want a ball python, terriblely;
I've been around my cousin's since it was a tinyy baby.
And I keep asking my dad for one, and he won let me,
how can I persuade him to let me buy one?

If your dad doesn't want one in his house, there's little you can to persuade him. Nagging or begging is only bound to make your dad irritated.

You'll just have to wait until you have a place of your own, sorry!

...I have two.
