Nikita and I were walking around the property when I spotted that interesting coconut tree.

“A recalcitrant tree,” I told her.

“What?”

Well, the rest of the trees went up for sunlight. This one said “Nah, I am going the other way”.

Nikita looked at the same tree and gave her verdict – “Cotangent!”

That is nerdier than me! And something that makes me very proud of her!
