>>29450463Important advice:
Figure out the main thing you want to say before you go and get used to it. When I went to my oshi's meet and greet, so many people didn't have a solid idea of what they wanted to say, and so in the end they just got nervous and said they felt "intimidated" by her for just existing. Apparently they all expected her to be different off-stream, but got extremely shocked by her genuine attitude being, well, genuine, to them.
So get your thoughts in order, figure out how to say it in less than a minute, and you'll be golden with time to spare. Also, bring like, a keychain if you have one. Apparently they love that stuff. Oh, and dress nice, don't look like a slob, be presentable.
