Peter shrugged. "I'm very sneaky?" He offered, to be honest it was probably just pure luck that people hadn't seen him crawling in to windows and things like that over the years. Either that or all of his neighbors knew who was under the mask and just kept his secret for him, either way it worked.
"I've got a strong constitution." He promised. Yes Carol would absolutely need to help him home, but he wouldn't throw up because Peter Parker never threw up, so they were safe. And he could tell Carol was dead serious about the sanctity of her jacket.
"I mean, there was an alien involved too, I feel like I'd have made very different clothing and hairstyle choices without the alien." Because sure everyone acted like an idiot in their 20s it was just part of life and growing up and becoming a real live adult but Peter's had been a little more influenced by a man eating monster.
His eyes went wide with delight when Carol admitted to having a perm once, "Oh my god, tell me all about it." He said leaning forward on his seat, he had an image in his mind but he needed to know more to see if that fit what he imagined. "I won't tell anyone, I promise." He held out his hand pinky extended to make sure she knew just how serious he was.
