So as AmazingPhil and Danisnotonfire say would you rather have your child be into creative writing or drugs? Creative writing should be the answers always! Always! (There's a pun for ya!)
This is a way to express such feelings for characters/ real people to do the things you want, or just to watch their ship canon. In a Fanfiction we can make the characters do whatever we want and no one in their right minds would call us crazy, because they know not only us, but more and other Fangirls will come after them. Just one tip: NEVER SHOW A REGULAR OR RELIGIOUS FAMILY MEMEBER!
1/2 of wattpad is probably made of fanfics. Plus if you write well enough you could even get up to over 1million!
But Wattpad also has just regular writing tips and regular (but amazing!) books!
Here's an idea if your into OUAT, do a CaptainSwan fanfic or maybe a Peter Pan fanfic. Things like that.
