Ohh, RayRay seems cool. I've never gone to a Con ( I'd love to, eventually ). Never tried Tegami Bachi, but maybe I'll try it.
Generally, if you're going to make memes about a certain, yet obscure subject, make sure you use an image where we can see what's going on and easily describable, and caption it simply. Someone hitting someone else over the head? "You can't just show your cat the dog", etc. It's a hard art, but if you look up "anime memes" you'll be greeted with stuff from "that's fine" to "why would someone make this".
I think you're at a ripe age, if I do say so myself. You can tell people about the things you remember while passing them on and getting into the new things, whereas the younger generation like me only know the new stuff. I'll eventually grow as old as you have and learn of the future world, but not right now. You have it good, I daresay.
Mm, when I buy manga I go to Barnes and Noble in-person. In January, they have a buy two get one free sale, so it's awfully good if you want to get presents for the grandkids (albeit late). That's how I grew my collection so quickly, and I've only been collecting for two years now.
