you and lily randomly became friends and you guys don't even know how did you both end up being friends. Now let's just say it's been 5 years you two are in 12th grade and still friends and she would always say random things out of nowhere like literally nowhere. Now one day after school you both were sitting on the bench and suddenly she just speaked

"marry me."

thats the random thing. And she was joking about it by the way. As she speaked while looking away minding her own business
