>I (23M) have a had a friend (22F) for a few months now. We went to high school together and were friends then. We weren't ever super close then, but we were friendly and hung out sometimes and did some school activities together. One of them was we were in the school play together. We never talked/saw each other after I graduated (she was the year below me).

They're not exactly lifelong besties. They were friendly in high school, lost contact immediately after graduating, and reconnected a few months ago.
