Sometimes when I am out mowing, some random person will walk to near to where I am cutting and just stand there and stare at me working. It sometimes looks as if this person has a question to ask me, and they are just waiting for me to get off my mower. But they don't make any hand gestures or anything similar if they really had a question. They just stand there and stare. I just wave to them (no wave returned) and continue cutting. I don't stop my work to talk to them. After a while they walk away. It's kind of weird if you ask me. It seems that if you went up to them, and asked "Can I help you" they wouldn't be worth the time for me to step off and talk to them, because they don't need any work done, they just want to watch. I see plenty of guys on zero-turn riders around here. Watching someone on one isn't that interesting to me. But could they just be fascinated by watching the zero-turns in action? Would you go and talk to them? Could it be a potential client? Or would you do as I have done- just give a friendly wave and continue working? Am I being rude? Just curious as to how you guys go about situations like this.
