Curiouser and Curiouser...

A question has come to mind over the last few days of being on campus again, and I don't quite see how it can make any sense. I've noticed, after a week of classes, that people have taken to using normal coffee mugs to carry their coffee around campus. As someone who takes coffee quite seriously and drinks it almost every morning of the week, I don't really understand how it seems like a good idea.

I'll use this morning as my example. It's not warm this morning; wunderground says that it is 42 degrees and there is a pretty chilly wind blowing. Walking to and from my 8am class I counted 6 people using normal ceramic mugs for their hot coffee.

Something quite like this.

On a good day, I have trouble keeping my coffee hot in mugs like these. Most of the time I have to reheat it a couple times so I'm not drinking lukewarm coffee. If I have problems keeping my coffee hot in one of these mugs while in my nice 68 degree apartment, how in the world do people expect to have nice, hot coffee while wandering around outside?

I don't get it.
