I’ve done this so much with both books and TV shows. I like knowing background of characters so I will search to read about it instead of finishing the book. Then regret it because I come across some type of spoiler. Also when I’m reading a series and stop in between books, either due to it being a current series or I haven’t gotten the next book yet, and I need a refresh on characters. Normally that’s easier to avoid spoilers but still can happen.
