Ugh! I do like one mixed couple (Alvin and Charlene) but I really hate Alvin and Simon pairings.
When I write AATC fanfics, I age them to 18, in High School, while trying to stay in the 80's universe as much as possible.
But, I don't follow the latest trends, I try to do my own thing(s) while trying to stay in the 80's universe.
I even have an OC (80's universe) With the 80's universe, I can see the use of OC's or Fan characters in them, as long as they aren't the CENTER OF ATTENTION!
But, anyway, I've written some on fanfiction.net As well as Deviantart.
