90 Day Wondering (1956)

In this animated cartoon an ex-soldier, quickly growing disenchanted with civilian life, considers the benefits of re-enlistment.

Ex-soldier Ralph Phillips, leaving his army camp, is ecstatic at being a civilian again, but finds that all his friends have started to raise families and that there is no place for him in his home town. Dejected, Ralph considers re-enlisting, and he's visited by two opposing figures, one advocating civilian life, the other arguing in favor of the military. The latter convinces Ralph to run back to the army camp.
