You can’t go home again. People try to return home, to their past, to their roots, but life doesn’t work that way. Sometimes, however, you do have to find its memory to improve your life today. Martin Sloan arrives near his home town and walks right into “the Twilight Zone” and his 11th summer. Once he realizes when he is, he tries to find his younger self, Marty, and reconnect with his mother and father.
The consequences are drastic and enervating, but his father comes to Martin to return his wallet. Dad knows who the older Martin is, but he urges Martin to leave. There’s only one summer per customer and this summer belongs to Marty, who shouldn’t have to share it.
Dad hypothesizes that Martin is wrong. Maybe, there are calliopes and merry-go-rounds near Martin, but he hasn’t been able to see them because he’s been too focused on the past and looking backwards. Dad says that Martin needs to start looking forward in his current life to enjoy his future.
Like Martin, we need to live in the present to enjoy the future. We can look to the past to draw strength, but it would be foolish to attempt to go back there… because you can’t go home again, even in “the Twilight Zone.”
