I can relate so much! Went to Uffizi once, I wondered why so many people were lining up to get in because I had zero clue about art at the time, after deciding to actually take a look in the museum with audio guide, I spent almost 4 hours in Uffizi though I didn't have many clues about lots of them, I was just trying to "feel" the pieces, years later, I finally started to read books about art and suddenly I had this amazing realization of "wow isn't that art that I've seen before?" then it all makes sense now, it's one of the best feeling ever, now I usually just go checkout museums, venues or whatever it is because I know even though I cannot appreciate the art at the moment, some day in the future I'll be glad that I take the chance to look at it.
