I'm cold. Put on a sweater.

Last winter was the coldest in 40 years in Hong Kong, with temperatures going down to 43F and the cold spell lasting 24 days. For those from my home state of New Jersey, currently experiencing wind chills as low as -10F, I know that sounds balmy, but very few apartment buildings in Hong Kong are insulated or have central heating, so it's often colder indoors than outside. At least Americans have a refuge in their homes. We're at the mercy of five layers of clothing and space heaters.

But this winter has been mild, and it reached close to 80 degrees yesterday. I wouldn't have known that from the temperature in my apartment, where it felt about 50, and I dressed for a cooler day but ended up stripping down to a tank top and carrying around my jacket and sweater.

So, it was strange to step into my building's elevator (I usually take the steps) and see tips for staying warm, when I was more concerned with staying cool.

The building management loves to put up advice and passive-aggressive admonitions, and I think they might secretly be Jewish mothers. Although I'm confused as to how much clothing I'm supposed to wear and exactly how much layering causes one to comically fall over.
