What I'm saying is...encouragements or hope to try. If she have a reason wanting to know him... it could be love at first sight... it worth to try.
As far as CI goes, I know many CI users wear it while working out. My wife use CI while she work out in our big gym. The only time she took it off is when she run on treadmill...she hate this noise. LOL.
So, remember he and she will be in the gym alot, in a same place, if she once understand what he trying to do then she can move on. Sometime when seeing thing as a mystery, no one couldn't resist to find an answer.
