Working on same exercise machines?

Is it weird that I only do cardio every time I go to gym? I do mix it up a little with dumbbells sometimes, but I'm usually doing exercise machines. The only time I do strength exercises is if I'm with my friend or brother. So, I'm wondering if people at gym think with, or whatever. Yeah, I don't mind them, but I've been wanting to ask.
