Stuff I like that some other people don't like:
reading for fun
sewing things like pillows, makeup bags and quilt-tops
spending time alone being quiet
cats
dogs
cloudy days
rainy days
lukewarm coffee
a club DJ spinning dance-y, trance-y music
simple, vegetarian food
going to my gym
long walks at night
small parties where I know most attendees
acting in live theatrical shows
almost anything on public television's Masterpiece series
Then there's stuff that other people love for which I do not see the appeal:
outdoor festivals or concerts
zoos
super-sunny days
snout to tail "food"
overwrought food with more than ten ingredients / heavy food
Wes Anderson films
food trailers
parties with a bunch of people I don't know that get so loud I get tunnel-vision
visual disorder, messes or chaos, which also give me tunnel vision
jogging or running, especially outside
95% of all reality TV
having my picture taken
baby showers / wedding showers - I'll just send a gift. I absolutely don't need to watch you open it.
monster-trucks
rodeos
