As the comments say:
No, a proposal like this isn't for everyone. But it's clear from her responses that she's not upset. She's marrying a guy who it appears went to clown school? ... Anyone who has that amount of enthusiasm for sheer, balls-to-the-wall adoration and love, I can't help but like. And it's touching that she's so surprised and ohmygod that she forgets her purse, but he runs back to get it for her.
