this is the sleepy signature smell

It's a good smell. Nothing better than opening new Yu-Gi-Oh card packs.
When I was a kid I collected these and PokΓ©mon cards. I had so many too. But one day I decided to just give them all away. I wanted to be a generous child of God. All the kids in the neighborhood were at my door fighting for which cards to get. Now I regret doing that. I wish I still had them in a folder somewhere. Altruism is retarded.
