When I was studying abroad in Japan during the fall, you know what I really wanted to invest on? A heated blanket!
Seriously! Those electrical heated blankets were something that I really really wanted to buy but ended up not getting it in the end. First, it was too expensive. And second, I knew I was not going to use it back in California so no point buying one to only use it for a few months.
But come to think of it, the idea of using a heated blanket was kinda scary too. What if you get electrocuted in the middle of you sleep?
Haha.. but in the freezing cold weather of Tokyo.. sigh.. it would definitely be useful.
