/jp/ - Otaku Culture

You must understand that happiness does not lie within things, but rather, within yourself.

Hello, /jp/ fellow Otaku culture appreciator here.
I want to ask you guys a question.
so here is how my history go....

>yesterday japanese friend invites me to his house
>i am like , ok dude lets go
>i'm advised to take of my shoes in the entrance
>his family is very kind and polite, they are very japanese like
>there's a little buddha statue in his room
>he left a few coins in front of it and then caressed the young buddha head.
>then we moved on to play some games

Why do you Otakus do this?
