Weird ass interaction at the gym

Is anybody else a pacer in between their sets or think it’s strange to do this? This girl just randomly walked up to me at the gym and asked me if I was okay and that I was pacing around and looked nervous. I was literally on my phone minding my business next to my machine walking in a couple circles because I hate sitting there for 5+ min at a time lol. Now I feel awkward and wonder if I really look like a weirdo doing this haha. It was such a strange interaction and it has me feeling weird lol..
