My dad, for nearly his entire career, had a flat top...and he looked good in a flat top. I emulated him in every way I could, but I could never get my flat top to look like his. This is how I always remembered him:
My dad was stern and very earnest about us getting our hair cut at regular intervals like he did, but when I was 14 after we moved back to the states, he let us do what we liked, and my brothers and I let our hair grow out long and bushy as it was done in the early Seventies...:)
