Is there anything that makes sense to everyone else, but not to you?

I found this on Quora. It’s not my question, but it’s interesting enough to ask.
Besides facebook questions like this, what is it that makes sense to everyone, but not to you? Something that everyone sees as normal or usual, something that everyone loves (or hates, doesn’t matter) but you just can’t get into it and see any sense as to why would anyone like/hate it or accept it as such. (a subject of love or hate)
