Eddie- He took you the diner that was in town. You two split the bill then afterward went to the park to talk.

Richie- He took you to the arcade and bought you pizza and paid for every game you did. 

Beverly- You both went to the quarry swam all day. After you were done swimming you both dried off talking about life.

Stan- He took you bird watching with him. You thought it was really boring but you didn't tell him. You ended up playing with his hair while he was looking at all the different birds.
