Definition:
Nostalgic- Longing for things in the past or not present.


Example:
“…the sheep bridge aspen grove was a secret place far from any road, a place only for me and my father. We visited it to perform the sacred rituals of fly fishing for the native redband trout and to drink from the spring in the grove using a rusty tin can hanging on a branch for that purpose…”
Netting the Sun, by Melvin R. Adams.


Explanation:
The author is reminiscing about times long past. He is remembering this place, and fishing there with his father, while longing to be back at that time. He recalls it as a very special place and time. His addition of details, like the rusty tin can, also helps us see his wishing to be there.
