This is how a boy say hi.

We were about to go to bed, then Aidan just bonked Nadia's head with pillow,

Daddy : "Hey, Aidan, don't do that, it's not nice to slam Nadia's head with pillow!"
Aidan : (ran and sitting down on the sofa with the pillow and smiled) : "I want to say hi to Nani, HI NANI!!!"

Nani is a name that Aidan calls Nadia with. He can say Nadia, but he'd rather call her Nani, he also call himself "An.... (read: end)" if he talks.

funny words

Aidan (yelling and running) : "Mommy..... bumbee bill!!! Help"
Me : "what, bumble bee ?"
Aidan : "bumbee bill!!!!"
Me : "okay, where is it ?"
Aidan : "there!!!" (pointing on the wall)
Me : "hahahah, it's not bumble bee, it's a fly!"
Aidan : "it's bumbee bill!!!!!"
