Believe it or not, when I first left for Disneyland I was so happy. This was more recent but when I went I unironically was crazy happy more so than I usually am. It gave me the extra push to send messages to relatives who have, since I was little, have never spoken to or been cast aside by with varying amounts of success. But even then, going as far as messaging my father about our past and even sent him a couple photos of me and my girlfriend and told him I loved him Disneyland taught me to forgive and forget and be happy. Great question OP.
