I got asked by a guy one time if I put turtle wax car polish on mine because it shined so much. I took it as a compliment.
On occasions I have sly lawyers appear in my court. If I have never met them before I always say something like " I see we use the same barber." It always gets a smile from everyone - even the non-sly dudes.
" I have always loved that line.
I don't care if you ask me, and I'm not shy to ask you! LOL
"Nice haircut!" or "You've got a great barber" something like that.
That's my usual way of acknowleding a fellow baldie. I find bald dudes to be pretty pleasant overall. Yeah, I wouldn't think guys with hair would ask each other about how they get their mops to look a certain way, but bald dudes clearly march to their own drummer and I find them to be much more approachable. It's like people of similar hobbies talking shop (car buffs, golfers, you name it).
I wouldn't be offended and I would hope for the same.
Just got back from Chicago yesterday. We went to a Sox game on Tuesday, I gave another Sly dude a hi-five when a home run was hit without even thinking about it. The Sox won, it was a great evening!
