Once you've reached your 2nd year in the game, go to Doug's Inn on a Saturday between
11am and 1pm. Inside you'll find Doug and Ann talking to each other. Doug is wondering
how long Cliff will stay in Mineral Town and he hopes that Cliff doesn't leave. Cliff
then walks in and asks what the two of them are talking about. Doug tries to keep
cool, but Ann blurts out and asks how long Cliff is planning on staying in town!
Ann tells him that he can stay at the Inn forever if he wanted to. Cliff thanks
them for their generosity and asks if they're sure about the offer. Both Ann and
Doug are very sure they would like to have Cliff around forever.
