Boundaries

My co worker behaved very well with me during the work day, but after work she walked with me out of the building and asked me why I wasn't into comic books and superheroes. I said they've never appealled to me. Suddenly she was cross examining me about why I'm so dismissive of comic books, fantasy and sci fi. She's concluded I'm very closed minded and not open to new experience. Given what I know of her background (she's lived with her family her entire life) I guess it takes one to know one. I finally shook her off without cussing her out (as she deserves) but the day is coming soon where I'm going to have to stop being polite and tell her to respect some boundaries.
