The whole day I'd see guys w/ smooth scalps, and I would see my reflection in a window or something and I felt out of place.
The only comment I got at all was a positive one from my cousin's husband who had also shaved his head and grown a goatee since the last time I'd seen him.
Did you ever shave late in the day and get an extra-close shave? It's really strange in the evening to find your head is still smooth when you're expecting to to start feeling rough.
