It’s a play on a format of post that goes:
I asked my crush out on a date x years ago.
Last night I just asked them to marry me.
They said yes both times and I’m so glad I had the courage to speak up.
As you read the story, you generally assume that they were dating and eventually got engaged. The picture shows a couple that you assume is them before you finish reading. Then you get to the line about how they said no both times and realize it’s not the typical boring engagement post, but a joke about being a creep.
I’ve always felt like people were overblowing the pocket lint thing, since I’ve never had it happen to me. Just realized that it’s because my pockets are too small, so the only pocket I can use is my back pocket with the port sticking out.
