Determination

I'm trying to do barnchores while the kids ride their bikes, but it isn't so easy.

Griffin: Me going to climb that tree.
Me: Griffin, why don't you ride your bike instead, Mommy can't catch you if you start to fall right now.
Griffin: No, me going to climb that tree.
(tries to climb tree, but can't reach bottom branch)
Griffin: Help me Mommy.
Me: Sorry Griffin, if the tree is too tall, then it is too tall for you to climb.
Griffin: Me going to climb that tree.
(moves his bike to the bottom of the tree and uses it to climb up, Hanna flies up the tree and joins him)

Me: You be careful there Griffin.
Griffin: Ha ha, me climb that tree.
