Me and my best friend were both fighting tooth and nail in the battlefield that is 8th grade highschool. Keep in mind, I'm a guy, she's a girl.
We came up with this amazing way to help each other in our own separate pursuits for reckless young ‘love’ (or, the sad excuse that is called 'highschool affections').
At lunch, I would sit at the table with the guy she had a crush on, she would sit at the table with the girl I was interested in, if anyone of us heard the 'target' say anything interesting about the other person, we would let each other know.
This method never really brought about any good information since neither of the 'targets' ever said anything interesting, but still, it was great fun to take part in.
