Fly fishing

The other day I bought some new underwear. It looked like my current favorite model in the packaging, and I was glad to be extending my laundry cycle. (Unlike a 90s-style politician, I will not be revealing what type of undies I wear -- although rest assured that they are both sporty and sexy).

Imagine my surprise, then, when I got home and discovered that they have no flies! I checked the packaging, and not a word about this design update anywhere. What the hell? Is this the new thing? Have I drifted so hopelessly behind the tide of fashion during medical training that I don't even understand underwear anymore? I don't want to get too hung up on this, but when you work a resident's hours convenience is very important.
