I think this is how I and many others feel when walking around everywhere. People can tell you work out and you notice how they are dying to say something. This may lead one to feel awkward, thus feeling the need to shoe-horn references about weightlifting into the conversation. You know, you may say things like, "Wow, I am really sore today" in hopes that someone asks you, "Why?" Or saying things like, "Oh, what time is it? I need to get home to do my push-ups." These are all good way to possibly discuss your weightlifting with others.
