I finished my story, I am a bit nervous about it tho anyways I wanted to ask if it can be necessary to include a Character's age or is that fine to leave out? Cause I was not sure if I could do that or if it wasn't necessary to put in. I did want to make an epilogue for the story on how each character I have in mind got their start in the business. or should I wait and leave those for after like a back story to real story.
Personally I would include the age. x
Life is not a rehearsal!! If you're quite clearly describing adults, then no need. If you're talking about students etc, where there could be ambiguity, then ages should be stated.
Please also note that people should act age appropriate, so you can't claim someone is 16, but have them act and sound like a much younger person (specific age play scenarios aside).
As the others have pretty well addressed the "age" issue with regards to Lush, "Junior" would depend upon the type of company. it could mean right out of high school and up, OR in other businesses requiring additional education... it would be older.
Now, as regards the "how they got their start" as you've said, it provides a possible starting point for ADDITONAL stories (in a serial) unless it is somehow crucial to the plot of the original.
Oh ok, I thought someone would be a junior in a law firm l was thinking like, maybe either 23 or 24, and Senior would be like I'd say around 30 or 33, Since the one that's 30 that;s thier the longest would be considered the senior. Like the Boss or assistant manager is.
