No, it’s not from the thrill of warm-weather romance (unfortunately).
In summer, I always have two outfits on hand (or on body). One is cotton and as skimpy as societal norms will allow; the other is woolen and as long as long-sleeved can be. The former is for walking to my destination, whether it be a movie theater, a library, or an office; the latter is for being in my destination. The drastic temperature differential between indoor and outdoor spaces leads to much bothersome, chafing, and eyeglass-discombobulating donning and undonning on my part.

To be fair, I err on the chilly side. (My mom, when I was new to this world, asked the pediatrician why I always looked slightly purple. The doctor responded that I had not yet adjusted to postnatal circulation. But nothing ever changed, so I guess I’m still adjusting.) But I also grew up in the Northeastern United States, so I am used to frigid, snowy weather. And though I have no official data, I have heard, over the years, similar reports from people of various body types and stages of fetal development: air-conditioned buildings are too freakin’ cold!
