I had a shave like that today. Same great razor as yesterday, same prep, same soap and brush, but I just wasn't doing well. Gave up after a pass and finished with a DE. Figured walking away was better than fighting it. Will do better tomorrow!

The other big benefit of being mostly retired is I have only my self and my wife to impress. She obviously has better issues to think about than my shave quality, so all is well!
