Spaceman

A lonely, space-loving kid named Aaron encounters a woman throwing out her junk from the attic who gives him a vintage toy space helmet, and ends up hearing a voice from someone — or something — trying to make first contact.
==Alternate Endings==
*The original ending: Aaron finds out the "alien" he's been talking to is the ghost of a dead boy who has been locked away in the attic by his mother, Ms. Hollinger, who was so distraught over her son dying that she didn't want to let him go. Aaron feels sorry for Ms. Hollinger's loss and decides to spend time with the dead boy in the attic, since he now has a friend who loves space travel.
*The alternate ending: Similar to the original ending, only Aaron is forced to play with Ms. Hollinger's son forever rather than volunteering to do it.
