You were on a field trip, you sat on the window seat and as the bus stopped at a gasoline station to let the others use the restroom, you saw the other bus from the private school just near your school parking next to yours.

A student named Heinz Cesare looked at you and smiled, he showed you his social media through the window before their bus left.

You decided to add his social media account, you became close and now he visited your public school.
