Forgive me for asking this...It's a FACEBOOK issue, and yes, I know how stupid that is, however. I recently found?

my brother has an adult daughter (our family is kind of weird) so I friended her on FB; she just bought a new fridge so we discussed that and she mentioned it came in different colors or "skins" and I said that was cool and mentioned in the1970s appliances came in two colors, Harvest Gold and Avocado Green. At this, for some unknown reason, she got snippy and explained all over again about the skoins that MAY or may NOT be available. Frankly I really don't give a sh*t about her fridge or the colors, I was trying to be polite and friendly and interested, now I want nothing to do with her, I want to delete her, is there ANY way to do that without doing the "unfriend" thing?

Thanks in advance.
