Unless I go to a reunion, party or convention, where I know I'm going to sweat and my hair will look as a mess in a couple of hours, I always shower in the night, waking up is a dare everyday, and the idea of just waking, then shower and then get ready scares me hahaha.
Also, if I shower in the night I don't waste time, which I do if I shower in the morning, valuable time I could spend, sleeping, for example
