Underwear

I just went to the bathroom (nearly 8:00 PM) and realized that my underwear are on inside out. Now, I put these on in the dark last night, so it is plausible that I didn't notice at the time because my room has an average temperature hovering around 20 degrees. So I change faster than the speed of light. But I've gone to the bathroom at least 3-4 times so far today and I'm just now noticing that my underwear is inside out? I must be out of it.
