While we expect to experience these discrete moments of recognition in ongoing relationships, they are not necessarily bound to any overarching narrative. They can be circumstantial, spontaneous, and without follow-up.
I think this is important to note and keep in mind, these moments don't just stop. People don't just stop giving you looks and wanting to get to know you better, and sometimes you might only have the one chance for your pathes to cross in that type of way. Sometimes the chemisty is best when it's completely unspoken and there's nothing more than imagination that's drawing you together and closer to someone.
