When I was younger, I reacted similarly to unfamiliar foods. Thankfully, I got past it because most of my favorite dishes are things I'd have immediately decided sucked. Glad I'm not missing out anymore.
When I was younger I had a hard time recognizing when people were making jokes and not really serious about things in light hearted conversations. Thankfully, I got past that because I now find a lot more humor in the world then I thought was there when I was younger.
But, I don't like the taste of pumpkin or butternut squash so it's not like I haven't tried it or like it's "unfamiliar" to me. But I really don't care if other people want to eat something I happen not to like.
