Lol. That puts me in mind of when I was an anime-loving teen and would get just... random anime things from family members for shows I'd never seen or of characters I didn't know. They'd just see "oh, it's an anime keychain! She likes anime stuff!"
I had about the same reactions to it, too. Like... I'm touched that you tried, lol.

Though it does seem like they should at least have noticed that you don't use other patterns. Ah well. It's the thought that counts and all, ha.
