Timing is key. My husband is out of the country right now and I have been going to the gym alone. I was in between sets today and this guy asked me if I was done with my sets. HELLO! I am still here, haven't moved. Obviously concentrating, breathing, taking a second. What you can draw from this is, while that guy probably wasn't trying to hit on me, TIMING IS KEY. If she looks completely into whatever she is doing, give her a second. Remember to look for wedding/engagement ring and respect that as well. I always make sure to wear mine, as I am 100% committed!
