I've never been to a Pokémon event. Growing up, I didn't live close enough to go to anything, and I couldn't drive myself or use public transit on my own to travel to an event (plus, my disposable income was obviously lower than it is now).
Now, I guess I could go to events, but I'm so conditioned to keeping my love of Pokémon under wraps in real life, for the most part. I also don't really have real-life friends who play/like Pokémon anymore, and I'm not sure if I would want to go to an event on my own. I've thought about trying to find a Switch/3DS group through something like Meetup to try to make some new friends, and I would love to play Pokémon with people, but most of the events I've found are on weekday evenings before I'm done working for the day.
