Who's lucas girlfriend?

Who is Private Jet and PooPoo?
They are lucas's girlfriend.

Lucas love to give a nickname to his girlfriend,
"private", "poo", oooh...an intimate name!
Haaaa...

"Lucas, are they pretty?" I said.
Lucas nodded gravely.

I asked lucas to show me who is Private Jet,
he pointed to a little girl in a photo,
who've got long blonde hair.

How about PooPoo,
she's a girl who've got long brown hair.

A brisk weekday

There's nothing like a NICE afternoon with the two little monsters!

That's the end of summer, I planned to visit them before Lucas' school life started. Lucas talked all day, Linus ate all day, I played all day, kakaka...
