Too soon

Walking through the kitchen, I overheard the following conversation:

Boy: Mine would have brown hair

Boy's brother: No, I think yellow. . .

Boy: No! Brown. And maybe green or blue eyes.

Boy's brother: I think, blue.

Boy: You can't choose! She's not even your girlfriend!!!

From what I could gather, they were discussing hair and eye color of fictitious dating prospects. It's too soon, boys. Too soon.
