Always has been the start of my preparation for the day. Showered and shaved, I'm ready for anything. I have another light shave before going out for an evening. Not often these days.
I shave before work - I'm 'lucky' :? in that I work shifts, so that varies the time of day I need to shave. Before early shifts I shave the night before as time taken to shave is wasted sleep time before it's light for me!
On days off I'll have an evening shave so I take my time, or a mid/late morning shave if we're going out so I'm presentable. Ish.
