Yesterday I was at the gym (I'm female btw) and did a looong run on the treadmill and some more cardio then when I went to leave this guy started smiling at me, like full on grinning, what does this mean
1. He was in a good mood. 2. He's a creepy guy who smiles at women at the gym. 3. He wanted to use the machine next. 4. You're overthinking things and need to stop reading into situations like these.
