Despite going to a 1300-person college, Peter and Kara didn't officially meet until their sophomore year in an Environmental Studies class. Kara thought Peter was cute. Evidently, Peter thought Kara was too, since he decided to shoot his shot and ask if she wanted to hang out sometime. They conveniently met at a party that night and the rest was history.
On July 13th (which was a Thursday), at 5 in the evening, Kara went for a run....and Peter decided that he was going to propose when she got back. He was planning to wait until Saturday, but the ring was burning a hole in his pocket. And after all, who doesn’t love a little spontaneity? When Kara got back, Peter managed to get her up to the roof their apartment building for “drinks” without raising too much suspicion. He then proceeded to start making awkward small talk but finally got down on one knee and proposed before his increasingly obvious stalling gave away the surprise. Peter doesn’t remember what he said, and nor does Kara, because they both blacked out a little! Afterwards, they went to their favorite Philly restaurant for dinner, and then they called their parents to tell them the news.
