Not born to shop

I was visiting a friend at her home when we saw her younger (teenage) brother leaving the house with a bag of cookies.

"Where are you going?" we asked.

"Birthday party."

"Oh, so you're bringing snacks?"

"This is my present."

"What?"

"This is my present."

"How old is the kid?"

"She's turning 16."

"You're giving a GIRL a grocery store bag of generic Oreos for her sweet sixteen birthday?"

"She likes these."

"Just because she eats them doesn't mean she wants them for her SIXTEENTH BIRTHDAY."

"But she likes these."

"They're not even wrapped!"

"No, it's cool."

"How well do you know this girl?"

"She's my girlfriend."

"Do you want her to stay your girlfriend?"

"But these are like, her favorite cookies."

"She may think it's sweet you know what cookies she likes, but she'll also think her boyfriend is a moron for handing her a bag of cheap cookies in front of a bunch of teenage girls at her SWEET SIXTEEN BIRTHDAY PARTY!"

He left the house with the cookies.
