You said stupid shit.

You transitioned with something negative, you are so "stressed"

You "looked up and down" her, following up with what I'm guessing was supposed to be sarcasm. But you don't know her, how's she supposed to get your sarcasm after you having said literally a few words to her? Looks like that backfired big time.

You "assumed" the friend "liked you too" which was overwhelmingly arrogant. What made you think the first girl liked you, never mind the second?

There's nothing you could have followed up with here. It was a car crash.

What you could have done differently is be nicer.
