Oh, look! I have a twin!

 Umm, Noah? I don't know how to break it to you but

I'm your twin... and that's just you in the mirror..

Nooo! You are a girl! Are you sure you are my twin?

What are you talking about? Look....

 We both like to eat everything around us, only twins do that!

 Ohhh, OK then!

Ok, then!

(*sigh*little brothers... you have to teach them everything!)
