I've received compliments on my hair from guys a time or two over the years I've been growing, but always from guys I was at least somewhat acquinted with.
The other day a passerby said my ponytail was great. Was nice to hear, and somewhat amusing considering it was braided at the time. Oh well, nice thought even if he was a little confused about the terminology [grin].

Well, at least he didn't say, "Nice bun!" -- or, worse: "nice buns!" (LOL)
