What is it?

Orange? Grapefruit? Lemon? or Lorange?

Typical to Florida, we thought we had an orange tree in our yard.
Marcus loves huge oranges, so I picked one (of 4)
He tried it and said it was part orange and part lemon a.k.a. Lorange
Our neighbor ask how we liked our grapefruits?
"Is that what it is?" I ask.
His wife digs her fingernail into it and the smell is definitely lemon.
I say it's Texas size... a reminder of home!
